18650 Battery Holder

Simple 18650 holder - made to hold 4 inline while being soldered/tack welded.
Their are two thicknesses - a 3mm should be around 17g (if you plan on leaving the holder on if you are putting this in a plane).

Note: I do not have any 18650 cells and have not printed this out so I do not know if it will fit perfectly or need to be adjusted (I included the Fusion 360 design file so feel free to change it up).

V2: Increased clearance of inner circle to allow for larger cells. Flattened one side to allow for easier mounting to flat surface.

V3: Made F3D file parameterized (change values of size of inner diameter and or wall thickness)
