Description

These are the 3d-printed parts for my Battery Tab Spot Welder Project (see )

This is my own take on the many DIY Battery Spot welder projects out there. Most of them are done using an off-the-shelf timer, or an Arduino, but as I had the parts lying around on my desk, this one uses a NodeMCU microcontroller. This project re-uses a 700W microwave oven transformer with the high voltage removed and replaced with a 2V, 350A secondary instead. The main voltage is controlled on it's way into the microwave oven transformer using a cheap Solid-State-Relay module.

The main box, print in PLA without any support, but with a 5mm brim for bed adhesion.
The lid, print in PLA vertically without any supports.
The front panel, print in PLA lying flat on the bed. Support material needed to fill the spaces behind the OLED display and the rotary encoder. Should be pretty easy to clean up afterwards.
Print 3x Aluminium Extrusion Clip in PLA, vertical printing, no support.
Print 2x cable grommets in Ninjaflex
Print 1x Hand rest in Ninjaflex
Print 1x Rotary Encoder Knob in Ninjaflex
Print 4x Feet in Ninjafles

Materials and methods

PLA and Ninjaflex required. Cable grommets, Rotary Encoder Knob, Feet and Hand Rest all printed in Ninjaflex - The rest in PLA

With the exception of the front panel, everything else prints without any support material (supports are built into the designs where needed)
