They work Great. Thanks :D
I have printed two.
The only thing I would suggest if you make two is to put a rod through the middle of both. this gives it more stability and makes it less likely to sag.
This is great to hold 2 more spools on the printer. You will need some room in the rear for the spools so they don't hit a wall or anything.
printed, came out looking good, everything snaps together like it should, but tolerances seem a little loose cause under the weight of the facecam it just sags...not sure if it was the settings i printed with or what...
