A simple stand / display for a hard case holder / protector, for playing and trading cards, with a couple variants. Made this to display select pokemon cards upright on my desk - designed to snugly fit the 'Ultra-Pro Magnet Card Holder'. I've included the solidworks file so feel free to adapt it and change dimensions as necessary.
The thing is sturdy with pretty much any print settings. Fits the card holder nice and snug.
Rotate it 90 degrees after importing into your slicer.
