Filament holder setup for Prusa MMU2S / Lack

thingiverse

I'm designing a super simple PTFE-holder/filament guide for my Prusa MMU2S, minus the pesky filament buffer that's such a pain to use. I've switched to using spool holders from https://blog.prusaprinters.org/mmu2s-printer-enclosure/, but ditched the filament buffer by repurposing the lack plate as the buffer instead. Since I already had a hole in my lack from back when I was pre-MMU, I came up with a filament guide that fits snugly into that existing hole.
