I have a server rack in my office - totally normal, totally healthy - and have a lot of junk related to the rack that doesn't go inside the rack. I thought I could attach an Ikea Skadis to the side of the rack as it was just the right size - but no such mounts existed to attach to the mount points on the rack.
Thus, I created this mount to allow attachment using the existing screws that come with the Skadis.
PLA works fine at 25% infill as long as the print is oriented so the layer lines aren't going to shear off.
