IKEA TOMTHULT bracket insert

This is probably really niche, but I'm proud of it, one of my first more technical makes
I found these narrow glass shelves abandoned outside and hoarded them away for the day I needed them, a few months later 3D printing enters my world in a big way and I realised they'd be perfect for my studio. I bought the IKEA TOMTHULT brackets as they're aluminium and simple and to make sure the glass won't rock up these little brackets insert into the bracket and the glass shelf slots onto and inside to secure them I just drove screws into the existing holes in the bracket straight into the plastic and it holds well
