I ordered a 3m roller blind which came with a rather large 45mm tube. Tube motors for this diameter tube come with more industrial fixings and drive adapters that aren't compatible with roller blinds tubes.

The idler required the dismantling of the existing idler to release the bearings and square ended pin. The brackets are slightly different sizes for the left and right. The size 10.2 and 10.4 are embossed into the rear of the brackets to help identify which side they belong to. I printed these parts at 100% infill for durability, probably complete overkill.
