Around our house, we like to rearrange things quite often, so we ended up with some modular wire shelves to store things in (C&A Home cube storage). However, we noticed that we did not have enough clips to arrange everything exactly how we wanted, so I took to fusion360 and designed these. 

I have only used the slim version so far and for me it holds on tight without being too hard to get on and off and without breaking. I have included some thicker versions that would take a little more filament and time, but might be sturdier if you are planning to hold your rock collection on a flimsy shelf or something of that sort and would like the clips to hold up better. The fusion file is also included if anyone wants to customize their clips with their own text or fun images (idk, whatever). 

I printed with pla using tree supports that only touch the build plate to make cleanup easier. I found that my overhangs were sufficient and the minimal supports allowed for fairly easy cleanup.

Please let me know if you found this model useful or have any suggestions for improvements. If you are really feeling it, please feel free to support me with a donation :)
