Roller blind end cap sencys

This is a replacement end-cap for a cheap sencys (praxis home improvement store brand) blind. The tube has an inner diameter of 24.4mm, so maybe it can be used for others as well.

It broke immediately on installation for me, so I can imagine this replacement might be needed by others. For that reason I share it.

If needed I've attached the fusion 360 file, so it can be adjusted to other sizes.
