Unbranded 3D printed amp knobs 2023

Eight 3D Printed Custom Red Bass Amp Knobs

I designed these replacement knobs for my Fender Rumble series bass ampifier as the original parts had become sticky and defective. Here you get Eight Galaxy Red knobs unpainted using the finest PETG plastic filament that fit perfectly on the Rumble potentiometers. These knobs should be generally compatible with a variety of other amplifiers but I specifically designed the hole size to the fit the Rumble amps. I developed this knob in Fusion 360 and printed on a Prusa MK4 in fine detail.
