No supports needed. Around 30% infill and 4 walls should be sufficient. I recommend using at least PETG though PLA-Plus may work too.

Should the focus ring be difficult to turn after assembly, screw in the Tairs focus limiter screw a bit more or move the grip back slightly.

You will need the following material for assembly:

- 2x bolts M5x20 or M5x25
- 2x bolts M4x10
- 2x nuts M5
- 2x heat inserts M4 (Model is scaled for Ruthex)

The bolts should be button, truss or pan head.
