Hexagonal dovetail minifig box!!! Based on AJsRaceway's TOTALLY AWESOME Modular Hexagonal LEGO Minifigure Display!! https://www.thingiverse.com/thing:3338499 (note AJsRaceway has not officially endorsed my design. yet).
I must admit I made my own dovetail square box and THEN saw the hexagonal design and became mildly obsessed with the hexagon. SUCH a great idea!! I'm hoping to make a rainbow so all my little friends can live in Cloud Cuckoo Land.
Design: based on AJsRaceway's design but done from scratch for ease of my software. Beefed up a little to make room for the dovetails. Embiggened a little to fit giraffe dude and Merbatman (Batmerman?). They have a hidden nail hole in the back. If it's balanced you can hang a whole wall sculpture on one nail! Mix and match colors, make it wild!
main: use this for most of the boxes
straight slots: fill in the holes since dovetails only slide in one way (this will make sense when you put them together)
no back: self explanatory I hope--use for style points or to cut down on plastic/time
straight slots no back: again fill in the holes with no back!
any (I used proto pasta PLA
print on it's back with supports touching the base plate. there will be small supports on the back of the male slides and the nail hole so pop these off and ready to role! (I tried having the slides go all the way to the back but it created a lip and wouldn't fit well into the slots so this works nicely).
