Summary I designed this to go on the base of my lamp. It is held by 3mm (M3) screws and nuts. Or this can be glued. (up to you) It is designed to hold a LIPO battery. With a size of no more then 75x40x17MM battery. The Battery i use is a (RC) Turing, 1000mAh, 1.0, 3 Cell, 11.1v . And i used strip LED's cut to size and weird to a switch. There is a gap for the base of the switch to sit in. The switch size i used is (excluding holes) this is just the contact size not the whole switch. 16x7x12MM (middle part) . 23x6x.5 (Whole switch size) I hope this helps others. PLEASE NOTE: I have not printed yet. But as soon as i do i will upload images. Print Settings Printer: DaVinci 1.0 Rafts: No Supports: No Resolution: 0.2 Infill: 25 - 30% Notes: Haven't printed yet.
