Acrylic Sheet/Plate Stand (For Pictures or Crafts)

This stand holds a 2.3mm piece of acrylic sheet upright. My brother asked me to design it based on an existing CNC cut piece of acrylic that came with the stand. 

I designed the gap to be 2.4mm in the slot and the sheet is 2.3mm thick, so it may be a tight tolerance. I had to really force it onto the acrylic, but at least I can be assured it's solid.
