Customizable Prusa MK2.5/MK3 to Filament Tube Coupler

This simple item will allow you to attach filament tubing to your Prusa MK2.5/MK3 filament cover. All connections are push-fit.

Customiser settings:

1. tube_od
- your filament tube outer diameter
- add some leeway if required (suggest 0.05mm)
2. coupler_ln
- length of coupling (filament push fit-depth)
- total length of the item = coupler_ln + 8.5mm (the filament cover bit)
