I remixed the lamp head for strength and a snug fit. I remixed the backpack to allow for a rocker switch.
All parts are oriented correctly and the correct size, but the Dummy 13 parts must be printed at 250%. You will need supports for all files except the head neck socket and the backpack wire hole cover. I used 3 walls and top/bottom layers with 20% infill. I printed using ASA for strength. The neck socket that snaps into the lamp housing (head) is a tight fit and will need a lot of force to insert.
You will also need some soldering skills to connect the wires to the switch and plug. Printing a base will make the lamp more sturdy.
Here’s a link to the switch and GU10 socket:
