16-40 mm Metric Tube OD Taper Gauge
A 76 x 90 x 6 mm pocket gauge with a tapered slot running from 14 mm to 44 mm. Push the end of a pipe, tube, hose or dowel into the slot and read its outside diameter from the tick where its centre stops. Ticks are every 2 mm from 16 to 40 mm, with long ticks at 20, 30 and 40, and their positions are corrected for the 11.3° taper. It covers the in-between metric sizes that hardware-store clamps skip, so you can buy or print the right saddle. A 6 mm hole lets you hang it.
Six-Module Gear Tooth Rack Gauge
This 130 x 50 x 3 mm card identifies the module of a stripped gear so you can model a replacement. Its two long edges carry 20° rack combs for modules 1, 1.25 and 1.5 (top) and 2, 2.5 and 3 (bottom), and you press each comb into the old gear until one meshes with no rock. The number of small holes beside each comb gives its module: 1 hole = m1, up to 6 holes = m3. Built for fan oscillator, mixer and blender gears. m1.25, m1.5 and m2.5 are close to 20, 16 and 10 DP.
118° And 135° Drill Point Grinding Gauge
A flat gauge for checking twist drills while you sharpen them. Lay the shank against the fence and slide it into the V: the right face is set at 59° for a 118° point and the left face at 67.5° for a 135° point. Each face has tick marks every 5 mm for comparing lip lengths. The body is 112 x 50 x 12 mm and takes drills up to about 13 mm, and there is a 5 mm hole for hanging it on a pegboard.
Stepped Wire Strip Length Gauge
A bench gauge with eight stepped lanes (5, 6, 7, 8, 10, 12, 15 and 20 mm). Push the wire into a lane until it bottoms out, close the stripper flush on the face, and you get that exact strip length every time, so Powerpole, Dupont and ferrule crimps come out consistent. Each lane has a 4.2 mm bore that takes roughly 20–14 AWG insulation (up to about 4 mm OD) and a 2.4 mm bore for 26–22 AWG hookup wire (up to about 2.2 mm OD). The block is 104 x 26 mm, and each lane's height shows its depth.
2-22 mm Taper Gap And Slot Gauge
A 152 mm taper gauge. The 3 mm thick blade widens by 1 mm for every 6 mm of length, from 2 mm at the tip to 22 mm. Grooves across the blade mark every 1 mm of width, with wider grooves at 5, 10, 15 and 20 mm. Slide it into a window-balance jamb channel, a bike dropout slot, a vacuum wheel fork or a door-check bracket until it stops, then read the width off the grooves. That gives you the size to order or model a replacement shoe, bushing or wheel. The handle is 5 mm thick and has a 5.5 mm hole for hanging it on a nail or pegboard.
PVC And EMT Pipe Size Slot Gauge
A 110 x 100 x 5 mm gauge plate for sorting offcuts in the bin or checking a fitting in the aisle. It has U-slots for Schedule 40 PVC in 1/2", 3/4" and 1" (21.3, 26.7 and 33.4 mm OD) and EMT conduit in 1/2" and 3/4" (17.9 and 23.4 mm OD), each 0.5 mm over nominal. A row of 3, 4, 5, 6 and 8 mm round-stock and hinge-pin holes runs across the middle. The pipe drops into the smallest slot it fits, and raised-free dimples mark sizes with no text: round dots for PVC, square dots for EMT.
Outlet Box Drywall Setback Gauge
A flat 120 x 45 x 6 mm step gauge for setting new-work electrical boxes flush with the finished wall. Three notches set the box's projection past the stud face at exactly 9.5, 12.7 and 15.9 mm (3/8, 1/2 and 5/8 in drywall); dimples next to each notch (1, 2, 3) show which is which. Rest the land on the stud, slide the box forward until its rim touches the back of the notch, then nail it, so you don't end up with recessed boxes that need box extenders.
Shelf Pin Hole Size Gauge Paddle
A 110 x 30 mm pocket gauge for older bookcases and cabinets. It has seven chamfered test pegs (4, 5, 6, 6.35 (1/4 in), 7, 8 and 9 mm) that you push into a shelf-pin hole to find its real size. Below them is a matching row of through-holes (printed 0.2 mm over nominal) for checking a spare pin before you buy or print replacements. A V-notch on the edge marks the 1/4 in peg so you can tell it apart from the 6 mm one, and a 6 mm hole lets you hang it on a pegboard.
Bolt Diameter And Pitch Gauge Board
A 150 x 58 x 8 mm bench board that identifies unlabelled bolts: nine ascending go-holes (4.3, 5.3, 6.3, 6.65, 8.3, 9.85, 10.3, 12.3, 12.95 mm — the smallest hole a shank passes gives its nominal diameter, including 1/4", 3/8" and 1/2") plus eight 24 mm thread-pitch combs on 3 mm raised ribs — top row metric 1.00 / 1.25 / 1.50 / 1.75 mm (M6, M8, M10, M12 coarse), bottom row imperial 1.27 / 1.41 / 1.59 / 1.95 mm (1/4-20, 5/16-18, 3/8-16, 1/2-13). Diameter plus pitch together separate metric from UNC, which a hole-only sizer cannot do; two 4.5 mm holes take M4 screws to mount it to the bench or a pegboard hook.
Seatstay Clamp Wheel Truing Gauge
A truing gauge that zip-ties to a seatstay or fork blade (12–28 mm round tube sits in the 90° V-cradle) so any bike becomes a truing stand — the 34 mm yoke gap straddles rims up to ~30 mm wide and five M3 screws running in 4.0 mm heat-set inserts act as adjustable feelers: four lateral (two per prong, 20 mm apart radially, so you can land one on the rim sidewall wherever you clamp) and one facing radially outward for hop. 104 x 52 x 12 mm, prints flat with no supports.
