I designed this system to be as sturdy as possible. Please note: The Dovetail joints are engineered for a very firm and secure fit (snug fit). It might take a little bit of force to slide them together for the first time, but they will hold perfectly without any glue! I’d love to see your setups – please share a photo of your printed boxes in the comments! If you have any suggestions for new modules, let me know. 🚀"
