Ghostbusters Proton Pack Attenuator

This was designed to be used with the attenuator add-on for the GPSTAR - Haslab Proton pack replacement boards.

This is a derivative work based on those that have also made proton pack attenuators. I used design elements from the MK3.1 q-pack files to inform the "ribs" on the attenuator body and to help make a non-crank Raytheon style knob (The final product shown uses a genuine knob) - (https://github.com/mr-kiou/q-pack)

This model does not require supports as it uses a sacrificial layer to allow the top layer to print. (Thanks Tacobeli for teaching me that method!)

I have added 3 additional bodies.

1. Has the radiation symbol meant for the lens add-on as shown below, but it has a bezel for the "slo-blo" lens.
2. Has a flush radiation symbol that is not intended for the lens, but just the symbol. This has the "slo-blo" bezel.
3. No radiaiton symbol, but a hole for another indicator light of your own choosing. Also has "slo-blo" bezel.

I have made a printable "Slo-blo" lens file or you can order the lens identified below (LEDTRONICS LCD780-TWF).

Post-processing:
Paint with filler/sandable primer. Paint to your liking and add stickers.

Radiation symbol light uses the marco lens from this kit:

I paint the symbol on the model and then glued this lens over the top.

"Slo-blo" uses:

Knob is a Raytheon 1.25" knob.
These can be sourced usually on eBay but no direct link is available. I have also included a mediocre .stl for the knob that is a derivative of the knob from the q-pack mk3.1 files removing the crank and just making a knob.

Back plate uses a belt clip:

I also used some plastic diffuser sheet from a broken LCD TV between the LED and the radiation/slo-blo indicators.
