The base can be a little bit tricky to assemble and could probably use an update, but this is what I'm rocking. You will need some short m3 screws to mount the ESP and a 20mm m3 screw to hold the base cover to the thread. You will most definitely want a ball end allen key for the ESP mount screws as access is tricky.
I printed the bulb in clear Formlabs resin and the rest in white hatchbox PLA on an MK3S.
***** DO NOT TURN OFF SUPPORTS FOR THE BULB *******
You will want to as it looks like it might work but as the print progresses the entire thing becomes like a spring and very small warping is magnified over and over. This springing effect causes issues on both FDM and SLA prints so supports MUST be enabled so that the bulb is not extending and compressing during the print. In my original attempt to print it on FDM the warping became so intense that the part broke the fan shroud off of my MK3.
Everything else prints great supportless oriented "upside down"
