I created this axle for the QIDI Q2 Top Spool Holder to accept a small roll (80g) of TPU. When using the standard axle from the design, the spool had a tendency to move back and forth and caused the filament to come over the sides of the spool and get tangled around the axle. This has fixed the issue for me, and I am able to reliable print TPU with the QIDI Q2.
The design was split into multiple parts to optimize print orientation for each section and minimize support needs. The flanged ends and center section are printed on their flat side without supports (you can support the center section to make the lower threads better). The "posts" are printed on their side with supports under the bearing shaft. No other supports should be needed.
1 x Center Axle
2 x Threaded Flange
2 x Flange Post
Once everything is printed, you will need to glue the post to the flange pieces. There is a small cutout in the flange piece that accepts the Post.
All connecting parts have a 0.2mm tolerance built in and should not require any slicer tolerance adjustments but use what works for your printer.
If you print this - let me know how it works. I plan to make some others for larger spools and will link here when available. If you have a request - let me know.
