Unmatch Box

### Unmatch Box

Unmatch Box is shaped like a matchbox, but is a combination of two linked rings. The goal is to pack the three pieces in the box. The volume of 2x3x4 is more than sufficient to accommodate all the pieces. The problem is very little room between the linked rings for the pieces to enter, once one or more pieces are in.

### Printing Instructions

Print one of each piece. After assemble 2 rings of the box as seen on the picture. Glue the joint of the inner ring and you are all ready for puzzling.

Some slicer / 3d-printers seem to have problems with the small hooks that close the ring. The hook is not connected to the ring. The important setting here seems to be “wall generation” or “perimeter generator”. This must be set to “Arachne” and not to "Classic". If all else fails, just scale up all pieces until the hook is properly generated.
