Dale PH-25 Volume Knob for Ghostbusters Proton Pack

A 3D printed replica of a Dale PH-25 power resistor to replace the Spirit Halloween knob on the side of the Spirit Halloween Proton pack. Rather than just have a passive replacement part, this replica part is designed to work as a volume knob for a volume control potentiometer and fits a splined 6mm Diameter shaft. This is explicitly designed to fit the volume control potentiometer that is included in my Spirit Blaster, Spengler Sound Board and Matty Blaster sound upgrade kits.

Works great on either the smaller Spirit Halloween pack or the Life-Size Spirit Halloween pack.

This knob is not intended to be used with the Spirit Halloween pack's original electronics since they do not have a volume control. It can be used without a volume control potentiometer if you just want it for looks to replace the unique "knob" on the side of the Spirit Halloween Pack.

The mounting instructions are quite simple and can be downloaded from here:

Thanks to Jason A. for the great suggestion to make this!
