I designed some simple mounts to get the Onyx heated bed mounted securely to the frame. The parts have been added to the GitHub repository. I’m not sure if I will be able to get enough mount points between the Onyx and the smaller mount to keep the bed from warping when it gets hot, I might need to shrink the size of the triangle to get it more secure.
Now that I have all the printed parts I will need for construction, deconstruction of the Rostock Max has begun.
The corner brace design I found on Thingiverse was too weak for 25mm extrusion. After assembling the frame the extrusion could flex the plastic touching it.
I took the design into Sketchup and adding more support. I’ve added the STL to a new GitHub repository I have started using for the pieces I redesign.
The new brace design adds support on the bottom of the extrusion to allow for 3 additional mounting points. This decreases the amount of flex present in the frame.
Side shot (The bottom holes needed to be reamed a bit because I sized them too small. The other pieces are sized correctly):
