Coupler for Ikea Bergshult shelves

This coupler will let you connect IKEA Bergshult shelves end-to-end without any gaps or end-grain showing. It's 20mm wide and has a 5mm central bar and it reflects the edge-trim of the shelf so as to be as unobtrusive as possible.

You might be able to print it on a 45 degree angle standing up to reduce the amount of support material needed but I found I got poor print quality trying to do that and got better results just laying it flat on the bed an using as much support material as is needed. I printed in ASA because the shelf is going to be in direct sunlight and I didn't want it getting yellowed or brittle but if your shelves are in the shade then any of the standard materials should work fine.
