Wanted something to carry some dice, figures, and a mechanical pencil, held together by magnets. The magnets can be purchased from Michael's, good luck finding which isle. Otherwise the holes have a 6.3mm(.25in) diameter and 3mm depth.
Print both halves. Press magnets into (4) holes, which probably have to be enlarged slightly.
If you print one please take a picture....
Printed in PLA @ 195C and the bed @ 50C.
