Free 3D Prints for the Prusa MK4 & MK4S

Printable upgrades, tool holders, and benchmark models for the Prusa flagship

Prusa printers ship half-built from printed parts, so it is no surprise the MK4 community prints its own ecosystem: side tool holders, spool systems, camera mounts, MMU accessories, and an endless supply of benchmark models tuned on Prusa's own profiles.

This collection gathers free 3D models for the Prusa MK4 and MK4S from Cults3D, MyMiniFactory, Thingiverse, and other platforms: printable upgrades and accessories, calibration and first-layer tests, plus the most-saved functional prints sized for the 250 by 210 mm bed. Every file is free to download from the original creator's listing.

The MK4's input shaper profiles make it a speed machine in PLA and PETG alike. Print accessories in PETG when they mount near the hotend or bed, PLA everywhere else.
