SummaryThis mod of the MMU2 part mmu2-pulley-body decreases the space aroundthe pulley axis and has more support guiding the filament than thestandard part.

When printing flexible filaments through MMU2 they tend to get stuck inthe pulley axis if there is even slight resistance either downstream, whenloading, or upstream when unloading.

For me, using this part has dramatically reduced the amount of jamming inthe MMU2.

There are two versions:

mmu2-pulley-body-mod is simply the modified standard part.

mmu2-pulley-body-modular has a hole in which you can mount the mmu2-pulley-body-module from beneath. The idea here is to be able toexperiment with different versions of the module without the need todisassembler/reassemble the entire mmu. (I have not tested this versionmyself!)

I usually print all Prusa parts using 0.15mm layer height, which works wellfor me, but standard print instructions (with 0.2mm layer height) shouldwork as well.
