I previously built a minifig display case but it was big, heavy, and awkward. It also did not have a glass cover in the front and seemed to collect lots of dust, so I decided to redo it.

The Tools

• Fusion 360 / Lightburn
• 60 watt CO2 laser
• staple gun
• drill (only for pilot holes)

The Materials

• 1/4 inch MDF
• 5x3mm circular neodymium magnets
• plexiglass
• support board
• sawtooth picture frame mounts
• epoxy
• hot glue gun

The Build

I decided to make it 5 columns 4 rows of minifigs so 20 per display case. The Fusion360 design is totally parametric (I think) so I can easily adjust these to customize it.

There are 3 types of material used. 1/4 MDF for the frame and shelves, the white support board (like you get from cheap bookshelves), and plexiglass for the front cover.

I used bolts for the 4 corners of the frame. I did not want to use glue. Here you can see the notch that holds the M3 bolts.

I used neodymium magnets, 5x3mm circles, to hold the front glass together. The 1st and 3rd shelves have notches where I used epoxy to glue 4 magnets to the shelf. There are also 3mm holes cut in the plexiglass. It’s kind of weird, but works and I didn’t have to use any hinges.

I used a hot glue gun to mount the minifigs using the engraged indicators for perfect spacing!

After the first one was a success, I made 2 more. Still need another one!

I used 2 sawtooth picture frame mounts per display case to mount everything to the wall. All done!

Mistakes

• probably could have designed the frame mounts in the other direction so the frame can sit flush on a flat surface

Updates

I created another size for my 4 larger minifigs. It really tested my parametric design, which didn’t do so well so I had to make updates.

I noticed that my MDF was pretty fresh, so it was dry and also not as thick as I spec’d it out for. Also, I put the magnets in the middle, but since there is only 1 shelf, it’s a little wobbly. Going to add stoppers the top and bottom to make sure the glass sits straight.
