No Support Required Customizable Dummy Battery (AAA, AA, C, D, user defined)

Easy and fast to print and come in all different sizes :-) Nice and basic design that can be used almost every where to bridge or bypass batteries in a battery holder.

Powering some decoration lights from socket instead of batteries with these. Great design!

Realy good and IT fits perfectly

Great design. This is easy to print, use as little filament as possible while the print still remain very rigid.

Just what I was looking for. These are a very tight fit using 0.8mm solid core wire at just one end of each. I think I'll scale them down slightly for the next set - the spring in the battery box should provide enough compression in most cases to ensure a good contact.
