Description
IF YOU LIKE IT TIP SOME! ;D PRINT SETTINGS print on side 0.2 mm layer high work fine to me infill 100% line width 0.4 I had flashlight working on 3 C cells, with spring on negative pole screw. So i take double 18650 cells and small bms for charging it from 5v micro usb. IMPORTANT ! ITS LITTLE BIT LONGER THAN 3 C CELLS STACKED! You can use it with or without bms. On positive (small hole) end i take out little bit of a wire, and put drop of solder on it. It's work just fine On negative i put some wire, and put small coin on it to not wrek wire by screwing plug. PRINT SETTINGS print on side 0.2 mm layer high work fine to me infill 100% line width 0.4
