Squirrelbrain Pi 4 Case Extrusion Mount modified to fit Bigtreetech CB1/CM4
This will also still fit the Pi 4.
Additional Changes:
Finally an awesome pi 4b mount that can take a 4010 fan and be mounted anywhere on the extrusions. Thank you Squirrelbrain - https://www.printables.com/social/135690-squirrelbrain/models
