A 3d printable case for the Arduino Spot Welder V3 from malectrics.eu
For more information on the Spot Welder you can also take a look at: https://www.instructables.com/id/DIY-Arduino-Battery-Spot-Welder/
Parts needed in addition to the 3d printed ones:
- 40x40x10mm 12V fan
- 4pcs M3x30 screws
- 6pcs M3 nuts
A detailed assembly instruction is available here:
New bottom part design added. The "CBM" in the filenames stands for "car battery mount".
With this parts you have two options to build the case:
- fully enclosed with extension cable as the previous version to use for example a 3s lipo battery to power the spot welder
- leave out the front part to make it possible to mount the spot welder directly to the car battery terminal with the case.
The case parts can be printed with 0.35mm layer height.
The rotary encoder knob should be printed with 0.2mm layer height to fit good.
Supports are only needed at the build plate. The ventilation slots dont need support.
