Hook kit for roller blinds or blinds

I have several roller blinds installed in my house, and several of the handles have broken because the plastic isn't very good quality... So, I decided to take action and clone and make my own design. They're working perfectly on my blinds, and not a single one has broken. I hope the design helps! I fully welcome any suggestions or ideas for improvements.I include the clip and two handles (one thicker) *The print profile it works perfectly, but I recommend increasing the outline layers and infill if it is possible. ¡Thank you very much!
