D6 Travel Dice Holder

Update 2023-04-01: Added a chamfer to the bottom of both the body and the lid (relative to print direction), and a recess on the bottom middle. Thanks for the suggestion, Florian Radlberger-Freude!

Cylindrical dice holder that holds 36x 12mm d6s, or 24x 16mm d6s. Knurled, screw-top lid. Has a hole running through the middle you can run a strap through for travel purposes (plus it keeps the lid attached). The slots on the side mean you can see your dice when it's closed, but also it makes it much easier to pull the right number of dice out.

For the strap: In the pictures, I used a spare shoelace, attached a large (M8 I think?) nut on one side, slid both ends of the cord through the body, attached one of those… cord tensiony slidery things you have on jackets, then tied it at the other end.

I printed it at a 0.1mm layer height, and the threads might need that (the knurling definitely does to look nice), but for the body, if you're using variable layer height, go nuts with everything up til the threads start – there's zero detail, so you should be able to get by with the largest number you can print with.

IMPORTANT: The threads on the lid should be printed thicker to prevent damage when screwing/unscrewing. I used 5 walls to achieve this.
