The "45" files are in recommended print orientation. Finish printed parts. Remove supports, file excess, sand, etc. Use 1.5mm drill bit to ream the pilot hole for the positive terminal. Secure positive terminal with an M2, 6mm screw. Push negative terminal into position - it will lock itself in place. Solder LiPo "+" wire (red), and TP4056 "BAT+" terminal to the positive battery terminal. Solder LiPo "-" wire (black), and TP4056 "BAT-" terminal to the negative battery terminal. Isolate battery from contact with TP4056 using Kapton or other tape. Assemble pieces within "Body". Secure LiPo & TP4056 with small amount of hot glue. Reinforce wires with hot glue. Glue "Panel" in place. File/sand as necessary to fine-tune the fit with your GameBoy. Technical notes The original GameBoy ran on 4xAA batteries, so the nominal power input would have been 6V. A 103450 LiPo pack however, only provides 3.2V-4.3V, depending on how fully charged it is. This is not a problem for the GameBoy DMG-01, because it contains an internal voltage regulator, which converts arbitrary inputs (within reason) to 5V. I've tested & confirmed this with a DC Power Supply, and confirmed that the GameBoy runs fine on all voltages a LiPo may output. The screen cuts out under ~2.5V, but the BMS board on the LiPo pack shouldn't allow it to discharge past 3.2V, to protect the LiPo itself from damage. Further, the power (W) consumption of the GameBoy does not vary significantly from 3-7V Print Settings Printer Brand: Anycubic Printer: Photon Rafts: Doesn't Matter Supports: Yes Resolution: 0.05mm Infill: 100 Filament: Elegoo Resin, water-washable Clear Blue Category: Toy & Game Accessories
