Lamp Bulb Holder Base

I designed a simple lamp socket holder to add a heater for an Elegoo Mars 3d printer.
It's designed to hold the following lamp socket, purchased at my local Home Depot.

The two parts bolt together using 2x M3 square nuts (the same as with a Prusa) and some M3 socket-head cap screws.

I did have to nip edges to make opening for the wires.

On my Elegoo Mars, this sits in the back right corner. I used foil tape to prevent the heater from damaging the plastic cover. I recommend using a relatively low-duty cycle for the heater. It only has about 10mm of clearance to the plastic enclosure.

I used a simple PID controller and 50W reptile bulb, due to the clearance I would not use higher Wattage heater. A Pt100 temperature sensor is mounted on the opposite side of the Z-axis. The chamber holds a nice steady 25C in a 12-18C unheated garage.
