Ultimaker 2 / 2+ Cam Holder

thingiverse

Mount the holder sideways and the base upside down. Secure the upper part to the base by either screwing it on with two M4 screws (10mm) or melting in M3 nuts that are specifically designed for this purpose. These special melt-in nuts make installation a breeze. Next, use the chassis screws at each corner to fasten the mount into place. The type of cam fixture screw you need will depend on the specific cam you're using - either a regular one or a custom-made screw that can be printed from the link provided: http://www.thingiverse.com/thing:578514. It's worth noting that this screw is slightly too small in diameter and the thread doesn't quite fit, but it gets the job done. When it comes to printing settings and material choice, there are no specific requirements for this project. I personally used white PLA with a layer thickness of 0.1mm, two perimeters, 25% infill, and a print speed of 45mm/s.
