If you collect or download my design, please give me a like :-)
This is a remix of jactre's nice Treasure Chest Gift Box. A bit scaled down (approx 90x60mm) and with holes for 4 Neodyme magnets (7x3mm) and with space for 4 self-adhesive rubber feets at the bottom.
For the connection of top and bottom I used a piece of paperclips.
Should be easy to print in the orientation provided in my STLs. Support not really required.
