The model itself can be found on Printables.

Description

The simplest travel case you can make. 😎

Both parts of the travel case contain 16 small 3 × 3 mm magnets that I bought on AliExpress. The magnetic connection is strong enough to prevent the case from coming apart during travel.

The model was printed on a Prusa MK3 using PLA.
