Update: Check out my improved model!
Do you want even more precise control over your Hercules DJ gear?
With this design, you’ll get a 1:2 gear-down reduction!
That means for every two rotations of the smallest knob, the large knob connected to your controller makes just one rotation—doubling your precision.
What You’ll Need
Print each file once (Base, Large Knob, Medium Knob, Small Knob)
1× 2mm O-ring or rubber band (40–44 mm diameter)
1× 2mm O-ring or rubber band (30–32 mm diameter)
2× M6×10 mm round-head screws
2× ball bearings (6×15×5 mm — inner diameter × outer diameter × height)
Double-sided tape
Printing Instructions
No special settings required. Use any solid filament you prefer.
Recommended: 20% infill with 3 walls.
No supports needed.
Assembly
Remove the stock encoder knob from your controller.
Apply double-sided tape around the knob area.
Attach the Base to the controller.
Push the Large Knob onto the shaft.
Insert a ball bearing into both the Medium and Small Knob.
Attach both knobs to the Base using the M6 screws.
Install both O-rings—place the large O-ring first.
I hope you enjoy my design :)
