Spinner Toy Free 3D print model

Simple fidget toy. Fun to play with if you're bored. The first model I designed did not have any fillets or smooth edges. I cut my self trying to get it to break loose. The tapered edge of the thread produced a very sharp edge. Anyways the part should be very smooth and spin freely. The higher wall thickness and infill would provide a larger mass. The more dense the part is the better it will be at spinning c: I printed the model shown and it is significantly smoother and spins faster. I printed the piece at 100% infill with 2mm walls and .8mm top/bottom layers. The part came off the print bed already broken free. No prying or twisting needed to break the two parts loose. I recommend using a little bit of vegetable oil between the contact faces. This helps it slide even smoother. Hope you are happy with the part c:

the model has a 0.8mm gap between between the two parts I print at .2 layer height
