Mount for MMU3 Cassette Compatible Buffer on IKEA Skadis

After some attempt to mount the great MMU3 Cassette Compatible Buffer https://www.printables.com/pl/model/572528-mmu3-cassette-compatible-buffer in my workplace I've decided to mount it on Ikea Skadis. So two simple mounts one on front and one on back. 

Print on any suitable material (DevilDesign PETG Red in my case)

Use support under Skadis hooks.

Additional hardware needed 8 x  M3x8 screw.

The files are for cassettes loaded from the left. For cassettes loaded from right you need to mirror the mounts
