This adapter is to be screwed to the PRUSA filament guide. Up to 5 materials can be inserted to make a manual filament change in case of missing the MMU3 upgrade for MK4.
I used my old MMU2 Buffer to store the loop after pushing back the unused material, which otherwise would hang around.
You can find a (German) description how to manage multimaterial printing without MMU here: https://forum.prusa3d.com/forum/original-prusa-i3-mk3-benutzermodifikationen-octoprint-gehaeuse-duesen/multimaterial-ohne-mmu/?_gl=1*1mzj12v*_ga*OTcyNzAxNDQ0LjE3MDQyNzA1MTQ.*_ga_3HK7B7RT5V*MTcwNDYyNDM5Ny4zMS4xLjE3MDQ2MjQ0MDIuNTUuMC4w
Hardware used:
2x. M3 Heat-Set Inserts for Plastic (or M3 nuts)
2x. M3 x 12 Screws
5x. PTFE Push Fittings
I printed it in PETG with layer height 0,2 mm
