Round USB A battery holder 18650 with TP4056 charger Here is a different type of charging instead of a micro USB power supply unit, a USB A port It does not matter whether it is a cell phone charger with USB A, power bank or PC, laptop ..., the main thing is a USB A that delivers 5 volts 1 amps. I saw a handicraft video on Youtube because it was made with a 30mm pipe, and thought it would be something for the 3D printer. Briefly thought about and done :) here is the result. I also used the spring design from YXC, with the modified minus pole guide. I unsoldered the SMD Leds and replaced them with an RGB 5mm LED, it has to be an LED with a common cathode connection. The USB A connector was glued in with 2k adhesive. I use 0.1mmx8mm nickel tape for the contacts. Have fun building it. RGB LED 5mm https://bit.ly/3GhuIgV USB A connector https://bit.ly/3r1Rjb0
