I would suggest to design it without the need to use bolts. Maybe two rods with snap-on ends?

@DaPi Good idea, some kind of dovetail may be good idea. That might go to v2 ;)
Thanks
Backlog from June 2024. Printed on Creality K1C using Creality Hyper PLA-CF. 3x wall loop, but less in-fill (cross-hatch around 25%).
Great model - both to print (no brim needed, sturdy with less material) and use (3M Command strips fit perfectly, rolls are secure from both sides).
@Impre3dvzla Ah! I missed that note in the Details tab. Makes sense. But I would say you should consider re-uploading the file with the model *already* in the optimum print orientation. That's definitely best practice. Anyhow, I am using the hook and it's working. If I need another, I'll be sure to print it vertically.
Good. Only issue is that because there is a small gap on the underside, whether you use supports or not, there is some significant bridging needed. Because of that, there isn't a nice smooth, completely flat surface for the 3M Command strip to interface with. This results in a not as strong connection between strip and hook. But worked pretty well anyway for a very light hanging item.
Edit: I printed this in the wrong orientation - so that was my fault. It's a good model. (edited)
@MakerCameron Hi, thanks for comment, hook was designed to be printed like on design picture, that is why the hook part by itself is not round, and part for attaching tape would be oriented vertically during print. (edited)
