The Lamy Safari's cap is held together by a plastic screw going into a brass bushing. The screw is fragile and can snap if too much stress is put on the clip.
This is a replacement for that screw. The thread in the bushing is M5, which is hard to print, so the replacement is unthreaded and taps into the bushing.
Print settings:
- Default STL has a 4.46mm screw shank. Adjust thread_dia in the included OpenSCAD and use trial and error til it fits
- ASA or any other filament with good inter-layer bonding like PA
- 0.4mm nozzle
- 0.1mm layer height
- 100% infill or 3 walls and default infill%
- As slow and hot as possible for good layer bonding without blobs
- may need to print one at a time if there is stringing or poor adhesion
Assembly:
Before putting the cap back together, form a thread in the screw using the bushing by hand. Once the screw fits the bushing by hand, reassemble the barrel.
