About this 3D model
I tried slicing and printing on PRUSA, Snapmaker J1, and Bambu X1C. In all cases the fit of the thread was a bit too tight. I imported the bottom into TinkerCAD at 101% and then exported as an STL. Fit is now perfect. My local library wanted to run an Easter Egg painting workshop for Elementary age youngsters. I went ahead and added some decorations to the sides in TinkerCAD. I printed in Overture Matte White as it can be nicely painted using Acrylic Paint Pens. Just finished printing 30 total. I can't wait to see what the kids come up with. Have fun!
