I initially switched from the original Prusa design to SteveS remix but there were some things I wanted to change in order to have a better experience with the filament buffer.
Changes:
- Both pieces:
- Added small holes with chamfers inside the hole for the PC4-M10 fittings
- PTFE tube snug fit to better align the filament to the path
- Words and numbers alignment
- aesthetics
- Minor design adjustments
- Added small holes with chamfers inside the hole for the PC4-M10 fittings
- Print piece:
- Added chamfers before the PTFE tube starts
- Better alignment when inserting the filament, making it easier
- Added chamfers before the PTFE tube starts
Printing:
I would advise printing the pieces with the orientation they are saved (text face up) with some supports. When printing text face down, one of the important parts, holes for PC4 fittings, needs support to print and will not be 100% right, making the PC4 fittings not inserting properly.
I used PETG at 0.2mm and 7% infill.
