Ghost Possessed 3D Printer. Glow in the Dark Filament Toolhead Charger

Help! A ghost took over my printer! 

You might see me arguing across social media about if this is Thermoluminescence.

Thermoluminescence from Wikipedia, "is a form of luminescence that is exhibited by certain crystalline materials, such as some minerals, when previously absorbed energy from electromagnetic radiation or other ionizing radiation is re-emitted as light upon heating of the material."

Well, respectfully, I don't know about your science, but it seems to track that a strange entity possessed my 3d printer and now is charging my filament!

Or maybe I just hired a ghost electrician to make my 3d printer seem like its possessed.

My friend also keeps saying my filament is not supposed to be this color when it exits the nozzle and that my 3d printer needs to see a doctor, so I bring this to you, 3D Printing Doctor! https://www.youtube.com/@3DPDoctor 

Inspired by Nathan Fielders Ghost Realtor episode...

Produces awesome green flash when printing glow in the dark filament. Great for Prusament Ultraglow!

Does not make the whole thing glow, just what comes out of the nozzle for a second or less depending on your layer size and other variables.

Still experimenting, but the thicker the layer size, the more Glow it seems to have.

I also took this design and adapted it to my toolhead directly and encourage you to do so as well! You will find the editable TinkerCad file linked on a video on my youtube channel in the near future. I will link that video here as well... but subscribe to my channel to make sure you don't miss out! (shamelessly looking for more subs on that channel :D )

I took 3x 3mm 12v UV light led's.
I soldered them into one wire that I then used  a JST connector and linked that to a buck convertor. I used another jst connector and solder split to attach the buck convertor to my hotend heatsink fan. 

I printed this in ASA for extra UV durability, but I'm not sure these cheap UV led's are really in the light range to do damage. I tried to make it so we did not have to look at the UV light as much as possible, and to minimize its exposure to your printer.

It sits on a bit of PTFE tubing before feeding into your hotend. 

Give me a follow on youtube and mastadon!
