Some huawei cables I have are relatively flimsy at the end (at least compared to other cables), and I wanted to add a strain relief to the ends to keep them from breaking over time.
This was also a test, because I just got some flexible filament (Shore 90A) and I wanted to see how well this could be printed on the Bowden-Prusa-Mini.
I ended up printing these standing upright on the printbed, and then slicing one side open with a cutter knife to insert the cable, then glueing it closed again (probably optional). Up until now they do a very nice job at evening out the bend right at the end of the cable.
