Brackets allowing for top/front-mounted spools for direct feed of filaments too soft/abrasive for the PTFE tubes.

Some rough (e.g. glow in the dark) and extremely flexible filaments bind up inside of the reverse bowden tube on the Prusa XL's extruder setup, often resulting in under-extrusion and failed prints. The solution for this is to feed directly into the extruder from above, which was a lot easier before I added an enclosure on my printer.
These brackets are friction fit on the front corners of the enclosure door opening and held in place by a dowel or PVC pipe that you can hang spools on.
You will need to cut a length of dowel or pipe approximately 455mm (17-7/8") long. Rather than measuring, it's easiest to just print/attach the brackets and then mark/cut to fit.
I have included 3 sizes that I think are the most useful. If you need something else, please let me know in a comment and I will add it for you.
- ¾" / 19mm
- Standard size for wooden dowels.
- ¾" internal diameter PVC (27mm outer diameter)
- This is the most appropriate size of PVC available in the US.
- 25mm
- This will fit either a 1" dowel or standard 25mm PVC used outside of the US.
As with most of my designs, you can find the source here at Onshape.
I'd still like to find a solution that works for when the enclosure is closed, so feel free to follow along or chime in with your own ideas/solutions in this forum post.
