2020 Extrusion Light Fixture

The 2020 extrusion mount is an extended version of the one I found in the "Webcam mount for common webcams - on Voron 2.4, Trident, 2020 extrusions" files on GrabCAD.  Mounting holes and counterbores were opened up for M4 screws.  Thank you, Ilia O.

I added a webcam to my printer, so that I don't need to go up and down the basement stairs as much, but this raised a new problem.  I can't leave the printer running in the dark anymore.  There is a light fixture in the room with the printer, but it's something like 6 feet (2 meters) away from the printer, and doesn't light up the build plate all that well.

I modeled up a mount and reflector to try and direct as much as the light from the bulb as possible onto the build plate.  I attempted to optimize it for my Ender 3, but the light diffuses a lot, and it does still cast a lot of light beyond the 230x230mm bed.  The light fixture will probably work for many printers.  The position of the light fixture can be adjusted in one axis, and along the 2020 extrusion, as necessary.

I might, at some point, chamfer the corners of the reflector, but I'm going to finish the enclosure eventually, and the one that I printed will probably get recycled.

I printed in PETG.  If you are using an LED bulb, and not printing in an enclosure, it probably doesn't matter too much.  Do not attempt to print in PLA and use an incandescent bulb.  Do not use PLA parts in enclosures.

Sorry, I don't don't have experience with any bulbs that you can buy in smaller quantities.  Yes, I know that I am using E12 bulbs with E10 sockets, but the bulb fits and works fine.  I didn't even notice there was a mismatch until just now.
