This frame was originally designed for my home lab rack that fits into one of those "four cube tables".
The STL files attached are multiple sizes to accommodate any size cube that you may need. I printed this in basic PLA and the tolerances are very tight on the dovetails so please make sure that your printer is well-tuned.
I have also attached the full STEP and fusion files for this design. it contains all of the components used to make this full home-lab rack. I didn't add all of the components as STLs because I don't think they are as useful or universal as the frame will be.
The author remixed this model.
Mostly inspired by this model. I remade everything from scratch but liked the idea and the design.
