IKEA Expedit/Kallax Record Spacer

I like my records to have a clean look from the front across all of the bins. I also like to prevent my records from sliding out of the back. Over the years, I tried a bunch of different hacks to make this happen, but once I figured out 3d printing I made my own. 

This prints in two parts and uses a piece of 1.75mm filament to join them in the middle for structure. I put a little glue on mine, but it's not necessary. 

To keep them from sliding, I use a bit of micro-suction tape.
