Prusa MK3 MK3S Extrusions

Hey guys,

just a quick sketch of the aluminium extrusions used on the original Prusa i3 MK3 / MK3S.

There are two lengths used: 205 mm (8,07") and 120 mm (4,72")

The holes in the corner have an diameter of 4,7 mm - tap yourself a M5 thread in each of them.

I`ve used carbon fibre PETG to print those with great success!
