This is a cable holder so that you can plug in your 90° angle adapter at the bottom left of the Legion Go and the cable goes flat over to the right, where you then clip it into the cable holder. This way the cable doesn't bother me and the charging socket is also protected.
The whole thing is hung directly underneath at the back when the kickstand is open.

its not finished, i allrdy work on it.. but i holds pretty good for me - maybe i change the size and form in future a bit =) but for the moment it works good for me =)

i printed it in pla with 15% infill. 

petg also works good =)
