Use with M4 bolts/nuts and your choice of Multiboard screw mounts. The rack perfectly fits an 8x panel front to back.
2 panels can be mounted on the 1u if they fall close to the middle of a u, but a 3u gives much more flexibility.
I thought about designing it for use with heat-set inserts, but thought that using nuts gave more flexibility and reduced the complexity.
I've include the f3d file incase you need something different. You can change how many u by changing the parameter.
The author remixed this model.
Redesigned the side panel mounts to attach to a Multiboard Panel.
