Battery Tab Spot Welder Project

youmagine

These are the 3D-printed components for my Battery Tab Spot Welder Project (check it out)\n\nThis is my own take on many DIY Battery Spot welder projects that exist. Most of them utilize an off-the-shelf timer or an Arduino, but since I had these parts lying around on my desk, this one uses a NodeMCU microcontroller instead. This project reuses a 700W microwave oven transformer with the high voltage removed and replaced with a 2V, 350A secondary. The main voltage is controlled as it enters the microwave oven transformer using an inexpensive Solid-State-Relay module.\n\nThe main enclosure was printed in PLA without any support, but with a 5mm brim for bed adhesion.\nThe lid was printed in PLA vertically without any supports.\nThe front panel was printed in PLA lying flat on the bed. Support material was needed to fill the spaces behind the OLED display and the rotary encoder. It should be pretty easy to clean up afterwards.\nThree Aluminium Extrusion Clips were printed in PLA, vertical printing with no support.\nTwo cable grommets were printed in Ninjaflex\nOne Hand rest was printed in Ninjaflex\nOne Rotary Encoder Knob was printed in Ninjaflex\nFour Feet were printed in Ninjaflex
