Printed Drive Parts
Worm axle, gears, spool, rod adapters and eye screw — the whole moving set
The moving printed parts, sold as one set because a gear train wears as one: the spool for cord blinds, an eye screw for wands, four rod adapters and the encoder magnet.
P/NTF-D-PRT-01SKUTF-D-PRT-01RevA
| Drive gears | Worm axle (2-start worm, 28T spur, hex end stub), motor spur (28T), crown gear (16T), rod gear (20T worm wheel + 11T pickoff) |

| Wand attachment | 1 in zinc-plated eye screw — threads into the axle's end stub |
| Rod adapters | 4 — 1/4" D, 1/4" hex, 7/32" hex, 5.72 mm square |

Features
- Sold as a matched set. Replacing one worn gear against the rest of a worn train just moves the wear. A fresh set is the actual repair.
- Cord or wand, both in the box. The spool and the eye screw are attachments on the same worm axle. Cord blinds take the spool; for a wand, the eye screw threads into the axle's end stub and the wand hooks on. Same drive either way.
- Fits the rods blinds actually use. Four rod adapters cover the common tilt rods. If yours is something else, generate one to print at tiltforge.com/adapters.
- Magnet included. The encoder magnet comes with the set: one 6 mm disc, magnetized across its diameter, that sits in the pocket at the center of the crown gear, over the AS5600. Either face up works. This is the only place it ships.
- Printable, forever. Every printed part here is in the STL set, and the eye screw is a hardware-store part. If TiltForge disappears tomorrow, you can still make one.
- An hour, not a service call. The whole set is the cheapest part of the unit. Wear is designed to land here on purpose.
How to use it
You hold this set to build a kit or to replace a worn gear train. Every step, in order: tiltforge.com/build.
- Pick the rod adapterTry adapters 11 to 14 on your rod and keep the one that fits snug.
- Set the crown magnetPress the 6 mm round magnet into the small pocket in the center of the crown's toothed face. Either face up.
- Slide in the rod gearPress your rod adapter into the rod gear and slide it into shell A, meshed with the crown.
- Snap in the wormSnap the worm into its cradle in shell A, meshed under the rod gear.
- Fit the axleSlide the hex axle through the worm, press the axle spur on the motor side and the cord reel on the front. They snap onto its tips.
- Thread on the clutchOn the shaft at the back, stack pieces 1 to 11 in order, Bellevilles alternating. Thin nut 10 snug plus one turn, then lock it with thin nut 11.
- Wind the cordBlinds fully open. Wrap each side of the cord 4 turns round the reel (3 at least), the two sides opposite ways, tails hanging down.
- Fit the eye screwTurn the eye screw into the end of the axle by hand until the eye lines up with the wand hook.
