Prototype Buzz Bee Jaguar clip

A prototype clip I'm designing for the Buzz Bee Jaguar, it isn't yet done and needs testing and refinement. Took measurements with calipers and tried to recreate it as best I can in Tinkercad, but it absolutely needs work and my printer is down so I can't test it myself. Please leave constructive feedback in the comments.

I have also uploaded a single barrel clip that uses similar dimensions for quick and cheap printing. Single barrel clip has had some further optimization done that should make it fit better. Once I get my printer working again I'll be testing these more.
