Update: 2019/01/12: Changed the shape and size of the "ears". They resemble the original shape more. Please try them out and provide some feedback in the comments! Thanks!

My wife's insulin pump clip is consistently breaking at the hinge hole, and replacement costs steep 10 Euros here in Germany. 10 Euros for a poorly designed clip made out of a bit of cheap plastic. So I decided to print one for her. Even if this would break even faster then the injection molded original, it is much less expensive and quicker to be replaced.

Thingiverse offers two or three clips from other users, but I found that they have made the hinges also very weak. Furthermore, they all try to reproduce the hook at the end of the clip. We think that this hook has no real purpose if you stick the pump onto your waistband. Doing so, you need some sort of friction resistance. I think my solution works pretty well and makes the clip a little bit thinner, so it bothers a little less. Additionally, this design can be printed without any support.

My suggestion is to sand off the corners of the print to make it more pleasant on bare skin.

If you have suggestions for even more improvements, please let me know.

Your opinion on this design and suggestions to make it even better is appreciated

Please also take a look at my other designs, printer parts, and tools.
