Description
Miniature of a Commodore 64 & Vic 20 with switch and working LED light.

Printing
For good quality, print the model with a 0.4mm nozzle and 0.16mm layer height.
For even better results, you can go down to 0.1mm.
For finer details, a 0.2mm nozzle is recommended.
In the photo, the C64 was printed using a 0.2mm nozzle and AMS, while the Vic 20 was printed with a 0.4mm nozzle and split into parts to be printed in a single color.
You’ll find 3MF files with build plates prepared for AMS printing, as well as a file labeled “mono” containing all the separate parts to be glued together manually.

Assembly
After printing, you’ll need a 3mm red LED (2mm is better), a coin cell battery holder, a small slide switch, and an 820-ohm (or 1K) resistor if using a 2-cell (6V) battery holder, or an 82-ohm (or 100) resistor if using a 3V battery.
Glue the components in place using a bit of hot glue and make the necessary connections.
A simple wiring diagram is included in the attached PDF.
Note: A 3mm LED is too large to fit cleanly into the hole and should not be forced or widened to avoid distorting proportions. I recommend filing down the top edges so it fits just 1–2mm into the hole, or gluing it in place to shine through.
For best results, file it down or use a 2mm LED instead.
