Second version of the Raspberry Pi (2 or 3) bracket holder for the Prusa i3 MK3 (original https://www.thingiverse.com/thing:3013148) . This one is sturdier and a lot less fiddly to handle. Might also work for other printers with same framesize as the MK3.
1 x base
2 x clamp + (any cable clamps if needed)
4 x screw
15 Jan 2019 update. Added mirrored base and cable clamps.
