This is a magnifying glass holder for the SKÅDIS pegboard from Ikea. Since it's unlikely that you will have the same magnifying glass that I do, I have also included a Step file. I usually model the tabs that fit into the pegboard at 4.8 or 4.9 mm wide, but this time I tried 5mm, which makes for a nice, snug fit. The part is printed upside down, so no supports are needed.
