3D model description

This model allows to power by wires a system with AA battery holder. The interest is to be able to insert (and remove) easily the simulated battery and to control for example the supplied voltage or to measure the current consumed.

The advantage of this model lies in

  • the industrial robustness related to the use of copper rivets (M4x10 or longer, easy to find at Ali for example)

  • the longevity of the wire assembly "in lockness".

  • plus a ring to hold the system during test manipulations for example.

Pass the wires and solder them with tin on the rivets 'end' then reinsert them. You can heat the rivet a bit and push it back into the model to adjust the overall length.

If you have only dome rivets, you need to sand one of them to make the negative pole

3D printing settings

PLA with 2 walls and progressive filling, Note that you have to adjust the "horizontal expansion" to get 4mm holes that tighten the rivet a bit (but not too much). For my printer, I put -0.1mm on this setting in Cura.

Using white material, the (+) can be colored with permanent marker to further avoid polarity errors.
