Double sided 3-way joint - Cube Assembly

This is a modification of my previous upload of a 3-way symmetric joint example, mirroring the joint onto both ends of the shaft. The orientation of the joints allows for sliding 12 parts together to form a cube. 1/100 of an inch was shaved off the joint parts on the .stl file to allow for putting together without much, if any, post print filing.
The part was also creating in OpenSCAD and made customizable using the Customizer app. The length and widths of the shaft, along with the tolerance, can be modified to your liking. Check back soon for vphotos of assembled cube!
Also, don't forget to check out my other (non-mirrored) 3-way joint. It's a great demonstration piece, and it only requires 3 copies to be printed, instead of 12.
