This air pressure pop-up cube is the ultimate fidget for all ages. It relies on a tight fit between the 2 oval pieces and the cube which allows them to function like a hydraulic cylinder that pushes the air from one oval to the other. You can either watch as the pieces slowly sink into their slots, or push down on one and watch the other side jump up!!! This is a great print to set on your desk to relieve stress and mesmerize anyone who picks it up. This was inspired by the cube made by the company Metmo who makes a wire edm machined block of steel that's over $300. It's a very cool product, but the price and availability made me create my own version for $3.00. There's a small air passage at the bottom that connects the two chambers and allows flow between them and gives the appearance that the pieces are connected. The print profile has a 15% infill for the cube at a fine layer height, and 50% infill for the inserts to give them some added weight.
The author marked this model as their own original creation.
