IKEA VESKEN bracket for joining multiple units

I have two Ikea Vesken shelf units that I keep my spools in, and thought I should model up a bracket to join them together for increased stability. Fit is loose but not floppy. If you want it tighter, you can always glue some fuzzy velcro on the inside.

I printed mine in PLA but any material should be ok.

Four brackets are included in the project file, one for each level of the shelf.
