I wanted to print a dice box but did not want to have one with a lid. 

The solution? roller shutter.

This model is highly reliant on the work of Michal Fanta at Printables which designed a wall mountable box.

I took his model and reduced its height.

I also added a wall in the insert so that there is a space to hold spare dice. If thats not want you want or want to edit the insert, I have included the blank insert.

This model requires four (4) parts, which includes one of two inserts (Part 2A or 2B).

I printed the whole model in matte PLA from Bambu Lab with no issues.

Note that you may want to reduce the number of shutter parts in the roller as it is heavy and can open by itself with a small push.

you will also need four (4) M3 x 20mm to secure the top to the bottom and complete the box.
