This is A split box for a Jenga game. https://www.thingiverse.com/thing:3060349 This version uses has holes for M3 screws and nuts for connecting the halves together easily and in alignment. Thread lock and some glue would be wise. If you don't have sets of M3 M4 and M5 screws as well as T-Nuts for all three buy some! I'm always dipping into my stash of them... Take note of the special allen wrench, it has a notch or ring that allows turning at an angle, its a big time saver. Also I used locktight on the project to keep things together.
