Replacement Shower Rose holder for 16mm dia. poles

Update:

31 Oct 2023: Added a STEP file of the model, as requested.

I made this to replace my parents' old shower rose holder which sports a (probably outdated) 16mm diameter pole. The original holder just wasn't able to hold its position on the pole, or maintain the rose's angle anymore. Commercial replacements appear to be mostly for 22-25mm poles. Sure, I know the use of the M10 hex bolt and nut may be somewhat old-fashioned in these heady days of all-AM (Additive Manufacturing), but I had that hardware on hand, and there are some applications where good'ol metal hardware just can't be beat for a quick and sturdy solution.

I designed this in Solidworks, and the partfile is included here if you want to try it for other sizes of poles. I employed a sort of ratcheting mechanism for holding the angle of the rose 'pocket'. This gives in addition to the vertical position, 5 forward (12deg steps) and 1 backward (15deg) positions.

I printed the parts in 0.2mm layers as aesthetics was secondary. The pole clamp is printed in its default orientation, while the pocket is printed upside down for better bed adhesion without a brim. From experience, I would recommend using supports only under the pocket's key tip which faces the bed, as shown in green in the sliced view. Reason is I printed this in PETG (recommended), and support structure is more difficult to remove, especially if they went inside the 'keyhole' channel. Paint on support blockers, and just rely on Prusa Slicer's bridging feature, which is the best-implemented on all the slicers I've tried so far (seriously, not trying to curry favour). I used 20% infill and 3 vertical shell perimeters.

Oh, did I mention you'll need an M10x30mm hex head bolt and an M10 hex nut? Noting the 'pointer' tip on one end of the 'key' on the pocket, align that with the notch cut for it on the keyhole, and insert it into the key channel. slowly turn the pocket anti-clockwise (viewed from the pocket end) until it clicks. This is the backward position. The next six clicks anti-clockwise are the vertical and 5 forward positions. You'll need to free the pole from its mountings so that the clamp can be slid onto it. Adjust it to height and tighten the bolt sparingly.
