18650 and 20700 battery tube
thingiverse
Here as a case for a lithium ion battery. I have attached an STL file for 18650 and 20700 batteries. The tolerances are pretty small so make sure your printer is calibrated, or feel free to adjust the tolerances in the provided OpenSCAD file. I recommend that you put the positive down when placing a battery in the tube. This way, if the top comes off, only the negative will be exposed. This should be safer. As always, be careful handling these batteries and use at your own risk. This tube carries no warranties.
