Hardware required:
- 5x M3 Springs (~10mm uncompressed)
- 5x M3 Washers (6.9mm dia)

- 12x M2 x 8 Button Head Screws

- 7/64" drill bit
I printed my copy out of ABS and vapor-smoothed it to post process it. I don’t see any reason that it wouldn’t work in PLA, but you will need to sand the edge hooks a little to get smooth motion. Here are the settings I use on a Bambu P1S:
- 0.16 mm layers
- Support raft
- Half speed
- Snug supports at 29-35°
- 3 wall loops (for vapor smoothing)
- Polymaker ABS (Bambu brand ABS does not vapor-smooth)
- Bambu Support for ABS
The hardware is somewhat flexible, but the M1.6 screws need to be very similar to fit the design. Mine are exactly 17.5mm long from one end to the other, with the head diameter of 2.85mm.
I tend to under-size my threaded holes so you might need a drill bit to widen them slightly.
McMaster Carr carries M1.6 screws with smooth socket heads, which will work best:
- M1.6 smooth socket head: Black Oxide, M1.6 x 0.35 mm Thread, 16 mm Long
These screws are readily available from Amazon:
- M1.6 socket head: uxcell 0.35mm Pitch M1.6x16mm
- Misc. button head: Kadrick 1230pc Metric Button Head Screw Assortment
- These 4mm OD springs from Amazon work well: METALLIXITY Compression Springs (0.5x4mm OD,10mm Free Length) 20Pcs
