These are copied by various lm8uu projects where I added holder to realize an all-in-one.
I realized them to be used on prusa i3 MK2/MK2S (and clones) y axis.
I personally tested T2 and T3 and I prefer T3. I'll give a change to T4 because I think they give me a better result.
There are three different bearing with ID 8.0/8.1/8.2 mm
- 2 M3x14 button head socket (DIN 7380)
- 2 M3 nylock nut (DIN 985/ISO 7040)
N.B. These are project for my new printer, currently I don't have any.
