MMU2 Filament Slack Wallet

thingiverse

This is an early solution for keeping your new MMU from jamming every time it tries to take slack from the filament. I was experiencing a multitude of problems and didn't want to mount the spools far behind the printer. This setup provides me with flexibility. Currently, I'm using it with the included OEM spool holders but plan to switch back to my pre-MMU setup for feeding this box. All I'm providing are the 4 brackets, along with two that fit the PTFE in case you need to print them with different settings to get a proper fit.

I've put a slight angle on the holders so the filament takes a bend in the proper direction, and attach sides as shown. Once the angle is correct, I secure it with a nail. This setup is still a work in progress and I'm open to suggestions!
