Check out this 3D-printed, full-scale model of a 105mm artillery round! Designed to perfectly fit into a real 105mm shell if you have one as a collector, this detailed replica brings military history to life. Whether you're a collector, history enthusiast, or military buff, this model is an incredible way to understand just how big these rounds are. For mine I glued all parts together except the tip, and poured sand into the model and then glued the tip on for an amazing realistic weight!

I set out to design a yarn holder and initially thought of using ball bearings for it to spin smoothly, but then I wanted something simple and accessible for everyone. So after a few iterations, I created a design with just three easy-to-print parts. Now, your yarn spins smoothly, just like it would on expensive bearings—no special parts, no complicated assembly, just a simple, functional solution. Let me know what you think!
