Meet DUFF, the DIN-mounted counterpart to TUSH.
UPDATE 2022-04-24: add a single layer (0.3mm) “cap” to screw holes so that they can be printed without support.
This is an undercarriage-style spool holder designed to mount on a DIN rail. I've found it to be both stable and versatile, plus it allows multiple spools of different widths to be mounted side by side on a single rail.
Version 3 fixes several shortcomings of the previous versions:
- Curved “retainer” section prevents feed issues with some new spools
- No need for threaded inserts or M3 nuts; screws go directly into plastic
- Added plastic bushings that may be used in place of 607 ball bearings (I recommend using PTFE lube)
