Modular building units

From growing up on LEGO technic sets and K’NEX, and working with elementary school students over lockdown, I was inspired to create a 3D construction toy of my own.

The unit itself is a simple equilateral triangle, based on triangular centric diatoms. I researched multiple forms of joining the units, and settled on my design as it was the most user-friendly, and lent itself well to printing. I plan to explore articulated print-in-place joints in the future, but the key here is being able to assemble and disassemble each part. The units are designed on Fusion 360, then resin printed. Below are the two versions I ran through, until I decided on an attachment method and design.
