These bumpers should be available on Amazon: https://www.amazon.com/dp/B003IMODW8

They have been designed to be used with M5 Low Profile screws (12mm), like the ones provided in Prusa Bear Upgrade Kits. They are available here too: https://openbuildspartstore.com/low-profile-screws-m5-10-pack/

I already had Sorbothane Duro 30 and I still using it with my MK2.5 Full Bear upgraded.
Because of the additional weights of vslots of this upgrade, I suggest to consider the model Duro 50 that is designed for a more important weight.

Please note that I have NO experience with these feets when printing high speed.
I can only share than they are perfect for me at speeds inferior to 70-80mm/s.
