1/4 3/8 1/2 in Drive Extension Bar Stand
A three-tier bench stand that holds socket extension bars, wobble extensions and adapters upright. You drop each bar's male square drive into a square port. There are eight 1/4 in ports (6.75 mm, for the 6.35 mm drive), six 3/8 in ports (10.0 mm, for 9.525 mm) and five 1/2 in ports (13.15 mm, for 12.7 mm). Each port has a chamfered lead-in. The rows step up from 12 to 16 to 20 mm toward the back, so the taller bars stand behind the short ones. The footprint is 136 x 80 mm.
Hose Reel Flexure Ratchet Pawl Retrofit
This one-piece compliant ratchet pawl adds a lock back to a hose reel whose internal auto-stop pawl has worn smooth. Mount it to the reel frame with two #8 (4.2 mm) wood or self-tapping screws. The 10 mm long, 4.6 mm wide slots let you slide the 10 mm sawtooth into the hub spokes or teeth. A 2 mm × 40 mm flexure beam springs the pawl back. A rigid stop wall 2.5 mm away limits how far the beam bends so it can't be overbent and break. Pull the 16 mm thumb tab to free the reel and wind the hose back in. The part is 54 × 64 × 8 mm.
Print-In-Place Ratcheting 8 mm Hex Nut Wrench
A ratcheting box wrench that prints in one go. It has an 18-tooth sawtooth hub and a flexure pawl built into the handle. The 8.25 mm through-hex fits M5 hex nuts (8 mm across flats) and lets threaded rod pass right through. To reverse the drive direction, flip the wrench over. It is 138 mm long and the head is 46 mm wide. The hub is held top and bottom by 45° bevel races, so it prints without supports.
1/4 3/8 1/2 in Ratchet Drive Wall Dock
A 140 x 46 mm screw-on wall plate with three bosses that stick out from the wall. Each boss has a square pocket for a ratchet's drive: 1/4 in (6.35 mm), 3/8 in (9.525 mm) and 1/2 in (12.7 mm). The pockets are 0.35 mm oversize so the drive's detent ball holds the ratchet, breaker bar or torque wrench with the handle hanging down. Gussets brace each boss, the pocket mouths are chamfered so the drive lines up as you push it in, and two countersunk holes take #8 wood screws.
Ratcheting M5 Hold-Down Star Knob
A print-in-place ratcheting star knob for M5 hold-down bolts and studs: a 4.5 mm deep captive hex pocket takes an M5 nut (8 mm across flats) over a 5.5 mm through bore, and an 18-tooth ratchet lets the 69 mm three-lobe handle sweep back and forth in tight spaces instead of needing full turns. The knurled 44 mm top collar stands proud of the handle so you can grip the rotor directly to back the bolt out; overall 69 x 69 x 26 mm, prints as two captured pieces with 0.45 mm clearances.
Print-In-Place Ratchet Lift Post
A print-in-place ratcheting height post: a 16 mm toothed column on a 50 x 50 mm bolt-down foot with a captured pawl collar that clicks up in 10 mm steps over 70 mm of travel and locks under downward load. Overall 110 mm tall; the foot takes four M4 screws and the support pad takes two M4 heat-set inserts (5.5 mm bores) so you can bolt a shelf, sensor or workpiece rest to it — pull the thumb tab to release and lower.
8 mm Rod One-Way Ratchet Clutch
A print-in-place one-way ratchet clutch: a 70 x 70 mm base plate (4x M4 clearance holes on a 57 mm square) carries a toothed housing, and a knurled Ø64 mm knob-hub rides inside it on three flexure pawls — turn it clockwise and it clicks over 21 teeth (17.1° per step), turn it back and the pawls lock against the steep flanks. The hub takes an 8 mm smooth rod (8.3 mm slip-fit bore) locked by an M3 set screw, so it works as an anti-backdrive for a hand-crank winch, gate or lift. 24 mm tall, prints as two captured pieces with 0.4–0.9 mm clearances, no supports.
Print-In-Place Ratchet Line Tensioner
A two-piece print-in-place ratchet winch for tensioning guy lines, clotheslines, tarps and cargo cord up to 5 mm — the 34 mm drum spins on a captured 10 mm post and a curved flexure pawl locks a 12-tooth ratchet every 30° (about 9 mm of line per click), with a thumb tab to release. Base is 78 x 58 x 4 mm with two M4 clearance holes on 66 mm centres for wall, post or trailer mounting; overall 78 x 58 x 42 mm, prints flat with no supports.
Flagged: lifting or tensioned load. Not for safety-critical use without independent engineering review.
