Thought I would share my current mount for my SMW3D R7 CNC. @Alex_Lee thought others might find it handy. I printed it in 50% infill 5 perimeter PETG. It is a printed part… but strong as heck in PETG. I cannot flex the thing if I try. I have the STLs but also the solidworks models (and I converted to step and x_t for those without solidworks if they want to take the design and modify it).
If you want a little detail of the machine it is on, check it out on this post: https://plus.google.com/+EricLiensMind/posts/Ns7CbQXAzn4
Or look over at SMW3D, @Brandon_Satterfield who designed the CNC is a super cool guy.
