Summary

I saw similar clips in a video and for some reason failed to find a model online. Decided to deign my own and after I was done I found the original clips that inspired me: http://www.thingiverse.com/thing:1646669 ;)

Can be difficult to print due to small size od the area making contact with the build plate - use brim or raft if needed.
