Dropper Seatpost Remote

Wanted to experiment with the necessary strength for this kind of mechanism. First iteration proved reasonably strong printed in PLA with 4 perimeters and 20% infill (gyroid). Should all print fairly easily without supports if you put the big flat sides down.

Currently uses more lengths/sizes of hardware than I'd like - Ideally, the whole thing would use only M4 screws (minus the necessary M5 nut for the barrel adjuster) and press-fit hex nuts. Redesigning the clamp would get me most of the way there.

While I haven't had any functional issues with it yet, I might experiment with different body designs to add stiffness - It does flex a bit under heavy cable pull. Supporting the bearing from both sides would be much stronger but pose a technical challenge for ease of assembly.

Hardware required:

1x 608 (skateboard) bearing

M4 screws: 2x 20mm, 1x 15mm, 1x 8mm (sizes don't need to be exact, an extra few mm here and there doesn't really matter)

4x M4 hex nuts

1x M5 hex nut (nylock, ideally)

1x M3x8mm screw

1x M3 heat-set threaded insert (working on redesigning this connection to use M4 with a hex nut)

1x M4x12mm washer

2x M4x9mm washers

1x M5 barrel adjuster (took mine off an old broken derailleur)
