I installed the squash ball feet mod on my MK4 inside of the Official Prusa Enclosure which raised the height of the printer making the original damper inserts too short. I have remixed them to make use of M3 screws of either 30, 35, or 40mm. The original parts made use of M3x20mm. I included pictures of all the different sizes.
The author remixed this model.
I made the Damper insert longer, made for 30, 35 or 40mm M3 screws for those who have made use of the squash ball feet in the enclosure.
