The file 'Vortex In A Bottle 3D Printed Cap 3D Printer Model' is (stl) file type, size is 171.9KB.
A great and easy to 3D-print bottle screw cap to connect two soda bottles together. Great for kids to make a vortex in a bottle! https://youtu.be/XdpwTa5dVms
Two sizes are available: 14mm and 8mm. The video shows the 14mm result. If you go for the 8mm you'll just have to spin the bottle harder to get the vortex going, but it will last longer!
Some printing advise: make sure to print the caps with support (20%) and 100% infill (solid print) and 0.15mm layer height would do just fine.
