LiIon 18650 Charger with TP4056 Module

Another LiIon Charger case. Biggest problem for me was until now, that good cotact to the LiIon battery was mostly poor. PLA is pretty brittle and not a good material for spring loads. So I decided to create a steel spring load with M4 screws and nuts. As TP4056 modules are different in make sometimes, I added a stl-file for experimenting the best fit with your individual TP-module, rework it with TinkerCad or whatever you prefer and make it fit. Similar thing with the spring assembly, therefore, another test file is added too. For finish I applied foam strips on the bottom side, and self-adhesive felt tape in the battery slot. 2020-10-17: Reworked a little bit. Print Settings Printer Brand: Prusa Printer: i3 MK3 Rafts: Doesn't Matter Supports: Yes Resolution: your choice, I took medium Infill: your choice, I took 25% Filament: doesn't matter PLA see photographs Notes: You can print the inserts in assembly postion bi-colored, but then you need some support material. Your print may most likely look better than my Edding marker red indication. Maybe I redo it. Category: Electronics
