This is a 3D model of a specialized adjustment tool for trimmer potentiometers such as the 3296Y-1-103LF and all other standard trimmer resistors with a regular adjustment screw.
How it works
The tool fits directly onto the adjustment screw of the resistor, providing a secure grip and preventing slipping during calibration. Made from plastic (non-conductive material), it significantly reduces noise and signal distortion compared to metal screwdrivers — this is critical when tuning analog circuits, power supplies, filters, and RF devices.
Features
Snug fit on the trimmer screw
Minimized parasitic capacitance and interference
Includes a split version — allows you to experiment with print settings, saving time and filament during test runs
Important printing requirements
The model contains a very thin feature measuring 0.6×1 mm. To obtain a functional tool, you must use precise settings:
Nozzle 0.4 mm
Line width: 0.45 mm
Layer height: 0.1 mm
Outer wall speed: 15–20 mm/s
Minimum layer time: 5 sec
Nozzle 0.2 mm (recommended for maximum accuracy)
Line width: 0.22–0.25 mm
Layer height: 0.06–0.08 mm (0.1 mm for faster printing)
Outer wall speed: 10–15 mm/s
Orient the model vertically (thin feature along the Z-axis). Set cooling to 100%.
