I want to make some conductivity testers and I don’t want to buy battery holders…
So I designed a box in tinkercad, 1 mm
larger than 2 AAA batteries (44.3 mm x 20.4 mm x 10 mm) and only 1 mm thick for the floor & walls. I also made it 5 mm taller than the batteries would be so that I can attach alligator clips to. It took 4 grams of filament and 10 minutes to print.
Biggest flaw is that I forgot the slicer settings were for brim
I added a couple of layers of copper tape across one end to connect the 2 batteries.
I also ended up adding some foil to fill in the space
I added 2 sets of strips at the other end that go up & over the top to connect the alligator clip. I did 3 strips each time.
I will add a third alligator clip in order to put the “test object” in the circuit.
