Halogen light arm mount

I had a pair of halogen lights and an AC transformer which I used to add lights to my CR 10 enclosure. I've been designing things for about a month so it might need some tweaking but I was successful in printing them and I am using two of them in my setup. They provide light and heat for ABS prints. I can go up to 50 C + ambient temp but try to stay below 45 to keep electronics happy.

To make one arm you will need a print of each part (base,arm,light holder and a hole cover) as well as:

2 x rubber washers - i used 5/16 M8 rubber washers, these are placed as shown in the last picture.
2 x M3x20mm and matching nuts - to secure the light unto the light holder part.

There are many knobs you can use but I printed 2 of these https://www.thingiverse.com/thing:769430 by B_EMME3D. Printing one as is for the M6 and resizing down for one M5. I epoxied them unto the the following parts:

1x M5x25mm bolt
1 x M6x13mm bolt

I put old locknuts under the M6 head to lift the bolt up
