The retainer cap of my roller blind broke - the part that holds the spring-loaded side in place. This is a model of the part, with dimensions taken from the original. It's a basic cheap no-name blind, but I would imagine this will fit a number of brands.

It should be a fairly tight press-fit into the blind tube, but the part with the spring should slide freely - some light sanding might be necessary to remove any printing artefacts.

Should be printed in the orientation of the STL, with supports on build plate only. There is a screenshot of my slicer showing the correct orientation.

In the photo, it is the black part (I am out of white ABS).

Printed perfectly in ABS+ with the standard Voron settings, but should be OK in any material, so long as the orientation is correct - if printed sitting on the flat side, the layers will likely be split apart by the compressed spring within and it'll fail in the same way as the original part.
