Yesterday I saw this excellent thread by Watts-on secondlifestorage.com/t-Watts-on-s-SpringSlot-18650-Battery-Holder?highlight=Spring
I like to tinker for entertainment and don't have a 3D printer, so wanted to see if it would be possible to modify a standard cell holder to have some of that awesome spring clip action.
After taking a close look at the cell holders and a pack of plastic clothes pins, I decided to give it a try...
Edited to add photos using phone
I made a jig out of wood scraps and finishing nails to hold the pieces in place.
Found that plain scissors will cut the plastic just fine. The red circle shows where I put a small notch in the cell holder to locate the spring for assembly.
Epoxy on the end of the cell holder. Add some weight to the clothes pin to hold it once it is in place.
I used a dab of epoxy on the spring to the bottom of the cell holder
Check for alignment and let it dry...
After the epoxy dries, I will see what happens to the spring end when I make some cuts so it will open.
