Battery Pack holder 21700

Battery pack holder for either 9 or 10 cells. Could be handy to assist in glueing or welding, to keep the batteries in place and well aligned. Use 2 holders and some rubber bands for double rows. I also included a simple cylinder the size of a 21700 battery, just to test the size in case you don't have the actual batteries at hand.

You may have to print to holders at 101% size, as the fitting is very exact, and my experience is that the prints (at least PETG) run a tiny bit small after cooling down.
