Under-Desk Keyboard Tray Slide Rail
A print-in-place dovetail slide that turns any flat board into a pull-out under-desk keyboard or mouse tray — 175 mm rail, 99 mm of travel, 27.5 mm total drop below the desk. The rail screws to the desk underside through four 4.5 mm ears (fits #8 wood screws, 4.2 mm shank, or M4 machine screws) and the 60 mm carriage takes three M4 heat-set inserts on a 20 mm pitch so the tray board bolts on from below. Print two, one per side, spaced to suit your board.
8 mm Rod 12-Position Detent Knob
A print-in-place indexing knob that clamps to an 8 mm smooth rod and clicks through 12 positions, 30° apart — for manual pan axes, jig stops, selector shafts and hand-turned leadscrew axes that need repeatable increments instead of free spin. The bolt-down stator ring (Ø50 mm, four M4 clearance holes on 60 x 28 mm ears, 79 x 50 x 30 mm overall) carries the detent notches; the rotor prints inside it with two 2.5 mm compliant spring arms and locks to the rod with an M3 heat-set insert and grub screw.
Bench Heat-Set Insert Press
A fully printed bench press that holds any soldering iron barrel 12–22 mm dead vertical so M3/M4 brass heat-set inserts go into printed enclosures square instead of crooked — no arbor press, rods or donor hardware. The 90° vee carriage rides a print-in-place dovetail column (0.45 mm clearance) and is strapped to the iron with a rubber band or zip tie in the 7 mm retaining groove; the 80 x 73 mm base has two insert trays and four M4 clearance holes to bolt it down. Overall 80 x 73 x 105 mm.
NEMA 17 Slew Ring Output Hub
A print-in-place rotary output stage for a NEMA 17 stepper joint: a Ø52 mm race bolts to the 31 mm square M3 faceplate pattern and sits over the 22 mm pilot boss, while a captured rotor clamps to the 5 mm shaft (Ø5.3 bore, M3 grub screw in a radial heat-set insert) and carries the arm on four M3 heat-set bosses in a 16 mm square. The printed race takes the radial and moment load that would otherwise destroy the motor's own bearings; total height 25.5 mm, two pieces, no assembly.
