V-Grip Drill Bit Depth Stop Collar
This slip-on depth stop collar fits any straight-shank drill bit from 3 to 8 mm. An M4 thumbscrew in a brass heat-set insert (5.5 mm bore) clamps the bit into a 90° V-channel, so one collar replaces a whole set of fixed-size stops. The 32 mm flange rests flat on the workpiece, which makes it good for repeatable shelf-pin, dowel and cam-lock re-drilling in flat-pack furniture repairs.
PVC Pipe Square-Cut Saw Guide
This saw guide has three cradles for Schedule 40 PVC: 1/2 in (21.3 mm OD), 3/4 in (26.7 mm) and 1 in (33.4 mm). A 2 mm kerf slot crosses all three cradles, so a hacksaw or PVC saw cuts the pipe square with no wandering ends. The block is 70 x 100 mm and has two M4 screw holes for fixing it to the bench.
Universal Toroid Winding Cradle
A bench cradle with a tapered double-V pocket. It holds a toroid or ferrite core upright while you wind it. The pocket narrows from 18 mm at the top to 3 mm at the floor, so it wedges cores about 3–18 mm thick, and the 36° end ramps centre any OD from a T-50 (12.7 mm) up to an FT-240 (61 mm). The winding hole stays clear above the 28 mm tall jaws. It also has a 1.5 mm slit to hold the wire tail, and the 110 x 50 mm base takes two M4 or #8 screws through 4.5 mm holes on a 94 mm pitch.
2020 Extrusion End Tapping Guide
A tap guide for threading the centre bore of 2020 aluminium extrusion. A 20.4 mm square socket with a chamfered mouth slides over the cut end, and a 5.5 mm guide bore about 25 mm long holds the M5 hand tap square to the profile, so butt-joint screws go in straight and don't wobble. Two sight windows let you check the extrusion is seated against the cap, and the part is 28 x 28 x 50 mm overall.
Square Edge Sanding Block With Fence
A hand sanding block with a built-in 90° fence. The fence rides against the face of a board, shelf or acrylic panel so the edge you sand stays square and doesn't round over. It has a 100 x 52 mm sole for a strip of PSA or taped sandpaper, a 15 mm-tall fence, and a 2 mm relief groove so paper and dust in the corner can't push the fence out of square. It prints upside down, so the sole and fence faces print flat, and the ribbed hollow body keeps it light (about 70 cm³).
Scroll Cam Three-Jaw Centering Clamp
A print-in-place scroll-chuck style fixture: turning the red cam ring drives three jaws in and out together, self-centering round work from 20 to 36 mm diameter (1/2", 3/4" and 1" schedule-40 PVC at 21.3 / 26.7 / 33.4 mm all fit) over a 20 mm through bore for drilling. 117 mm across, 24 mm tall, with three M3 clearance holes (3.4 mm) on a 104 mm circle to bolt it down to a bench or drill-press table.
Quarter-Sheet Sandpaper Cutting Jig
A slotted bench jig that cuts a standard 9 x 11 in (229 x 279 mm) sandpaper sheet into exact 1/2, 1/3 and 1/4 sheets for palm and orbital sanders: register the sheet against the 6 mm fence and run a utility blade down the 3 mm guide groove at 93.1 mm (thirds), 114.3 mm (4.5 in) or 139.7 mm (5.5 in) from the fence face. 154 x 100 x 15 mm open-frame plate with a perpendicular squaring fence, dot markings to identify each groove, and two 4.5 mm holes for #8 wood screws so it can be fixed to the bench.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
Five-Size Hand Tap Guide Block
A bench jig that holds a hand tap perpendicular to the work while you start the thread, with five guide towers bored 3.4 / 4.5 / 5.5 / 6.6 / 8.6 mm for M3, M4, M5, M6 and M8 taps. Each bore is 30 mm long (a ~9:1 guide ratio on M3) with a 2 mm funnel counterbore at the top; the 116 x 40 x 5 mm base sits flat on the workpiece and has four 5.5 mm holes for M5 clamp screws, and 1-to-5 tally grooves along the front edge mark which tower is which.
Bench Wire Bending Lever Jig
A print-in-place lever bender for forming hooks, eyes, J-bends and brackets from soft wire and rod up to 4 mm (aluminium, copper, brass, annealed steel, TIG filler): the wire slides into a closed 4.6 mm guide channel, and the swinging arm wraps it around a 16 mm die for an 8 mm inner bend radius. The 85 x 48 x 8 mm base bolts to a bench through three M5 clearance holes (5.5 mm); overall 149 x 48 x 31 mm, lever prints captured on the die post — no assembly, no fasteners in the mechanism.
Brake Line Roller Straightener Block
A five-roller straightening block for 3/16 in (4.76 mm) brake, fuel and copper-nickel line: three 624 bearings on the lower row and two offset above squeeze the tube to a 4.2 mm nip (0.56 mm set) so coiled line pulls through dead straight. 110 x 44 x 18 mm body with V-groove entry and exit guides, 3.4 mm self-tapping holes for M4x16 socket-head screws (the 7 mm head clamps only the bearing's inner race), and four 5.5 mm M5 holes to bolt it to the bench — or grip the 9 mm plate edges in a vise.
Flagged: hydraulic brake system. Not for safety-critical use without independent engineering review.
Bread Loaf Slice Guide Frame
A portal-frame slicing guide for home-baked bread: a 130 mm wide loaf channel (takes a 9x5 in pan loaf) with eight 5 mm knife slots on 14 mm pitch, so every slice comes off the same thickness. The loaf deck sits at z=7 mm while the side rails top out at z=5 mm, so the blade passes 2 mm under the loaf and cuts the bottom crust clean before stopping on the rails; overall 140 x 149 x 44 mm with a 24 mm backstop to push the loaf against.
Print-In-Place Pantograph Copier
A four-bar parallelogram pantograph that prints fully assembled in one piece — four bars on captive pin joints, no fasteners to add. Trace an original with an 8 mm stylus in the tracer socket and a pen in the output socket draws it at exactly 2:1 scale; both 8.3 mm sockets take an 8 mm rod or pen barrel and have M3 self-tapping pinch screws. The fulcrum eye takes an M4 screw to anchor it to the bench. Overall 169 x 68 x 19 mm.
Hinged SMD Stencil Paste Jig
A print-in-place hinged jig for applying solder paste through an SMD stencil: the 95 x 80 mm base deck has a 70 x 50 mm pocket 1.6 mm deep that holds a standard FR4 board flush with the deck, and a 95 x 62 mm frame folds over on a 5 mm print-in-place hinge so the stencil stays registered while you squeegee. Two 11 mm ejection holes push the finished board out from below, and two M3 clearance holes tie the jig down to the bench.
Self-Centering Hinge Screw Drill Guide
A three-station replacement for a Vix-style self-centering bit set: drop a cone into the countersunk screw hole of a hinge leaf, drawer slide or strike plate and the 20 mm-long bore guides your pilot bit dead on centre, so screws pull the hardware where you set it instead of drifting. Cones suit countersinks from about 7 to 19 mm, bores are 2.9 / 3.4 / 4.5 mm for 2.5, 3 and 4 mm bits (1, 2 and 3 engraved dots mark the size), and the whole bar is 96 x 26 x 18 mm with scalloped finger grips.
Axial Lead Bending Pitch Jig
A 136 x 26 x 14 mm bench jig for forming the leads of axial through-hole parts (1/4 W resistors, diodes, small caps) to exact PCB hole pitch: lay the body across a rib, press both leads down the sides, and the lead centres land on the 2.54 mm grid. Six ribs give 5.08, 7.62, 10.16, 12.7, 15.24 and 20.32 mm (0.2–0.8 in) pitches — each rib is milled 0.6 mm under its pitch so the bent lead diameter makes up the difference — with 3 mm relief slots through the 4 mm base so long leads pass clear, and two M3 clearance holes 122 mm apart for bolting it to the bench.
32 mm Shelf Pin Drilling Jig
A 148 mm self-registering drilling jig for the European 32 mm shelf-pin system: five 5.4 mm guide bores on exact 32 mm centres, 13 mm deep for bit alignment, held 37 mm from the panel edge by an 8 mm deep hook fence. Leapfrog it down a cabinet side by dropping a 5 mm shelf pin through the end bore into the last hole you drilled; two 4.5 mm M4 holes let you screw it to a backer board or wooden fence extension.
Round Rod Cross-Drill V-Jig
A 70 x 26 x 34 mm V-block jig that holds 6–14 mm round stock (8 mm smooth rod, dowels, tubing, 1/4"–1/2" bar) and guides a hand or press drill straight through its centreline — the 90° internal vee self-centres any diameter in Y, so the bit can't walk off the crown. Three guide bores (3.4 / 4.5 / 5.5 mm, 10 mm deep) take 3, 4 and 5 mm bits, two M4 heat-set set screws clamp the rod, and a stepped relief slot under the vee lets the bit break through without drilling the jig. Flat parallel sides let it sit in a bench vice.
Cabinet Pull Drilling Jig
A 178 x 50 x 8 mm drilling jig for cabinet door and drawer pulls, with 5.5 mm drill guide bores laid out symmetrically at 76.2 mm (3 in), 96, 128 and 160 mm hole centers plus a single center bore for knobs. The 6 mm fence rib stands 10 mm proud and registers on the door or drawer edge; the two bore rows put the holes 20 mm or 35 mm from that edge, and a 4 mm centerline trough lets you line the jig up on a pencil mark.
Over-Center Push Toggle Clamp
A print-in-place four-bar over-center toggle clamp (125 x 46 x 26 mm) that pushes a 24 mm wide pad sideways to lock a workpiece against a fence — handle, coupler, arm and base all print as one piece on printed pivot pins with 0.5 mm clearances. The base bolts down with two M5 clearance holes plus two 20 mm M5 slots so the clamp can be slid to the work on a T-track, 2020 rail or drilled bench top.
18650 Four-Cell Pack Jig
A 44 mm square block with four through-bores (18.7 mm, on 20.6 mm centres) that holds four 18650 cells upright, parallel and bottom-flush against the bench so nickel strip lands square during spot-welding or pack glue-up. Open-topped grab notches — one per cell, in 4-fold symmetry — let you spin a cell to set polarity, and two 5 mm ears with M3 clearance holes bolt the jig to the bench; overall 68 x 44 x 26 mm.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Five-Size Drill Guide Block
A handheld drill guide with five tall bushing towers (3.2, 4.2, 5.2, 6.4 and 8.2 mm) that keep a bit perfectly perpendicular, plus a 90° V-groove underside that self-centers the holes on dowels and round stock. Block is 102 x 36 x 44 mm.
Right Angle Corner Clamp Jig
An 80 mm L-block that holds two boards at a true 90° while glue sets, with open windows so a spring clamp reaches straight through to the workpiece and a rounded corner relief for squeeze-out. Two 4.5 mm holes let you screw it down to a bench or assembly board.
