This replacement roller holder helps to print your roller holder for your blinds.
My original part was broken. I didn't want to buy whole new repair set, so I did this little model.

Durability of this thing is still in testing. I printed myself a few options - on flat surface, without any rotation.
with 9 and 45 degrees - After a few weeks I will try to remember to get back with results
