About this 3D model
Boost Me See the project here https://hackaday.io/project/188800-classic-hp-calculator-lipo-battery-pack-enclosure Print the enclosure with the provided STL files. Although Tom provides a link to PCBWay to order directly this won't work since it is NOT THE SAME PCB. I have NOT yet published the PCB. I used four M2 x 8mm screws to close the enclosure and one fragment of transparent 1.75mm filament as a light guide for the LED. The STLs can be printed on an FDM 3D printer but for best results I recommend using the SLS capability of your PCB provider. I had good success with JLC PCB (not sponsored, just a happy customer) and their SLS black nylon for other projects. New photos when I receive the parts. The enclosure is licensed CC BY-NC-SA
