I printed the box in Prusament PLA with 0.15 layer height speed profile on MK4 MMU3 (no space for purgetower - so it's a single color print).
The magnets require a bit of force to be inserted. I used a hard object to press one side into the insets. No glue required. I placed the magnets for the other side onto the first magnets which helps with the polarity and closed the box to press the magnets into the other insets (see pictures).
I printed the wood pattern model with sunlu wood pla. I had to set the temperature to 195°C for the first layer and after that 200. I also had to use the smooth PEI sheet, otherwise the filament wouldn't stick.
The author remixed this model.
I added insets for 6mm x 2mm round magnets to hold the box closed without having to use a latch on the front.
I liked the wood look from VibroAxe so I added a file which adds the wood pattern to the dicebox with magnet insets.
