UNI-T UT18C Protective Storage Case / Holster

A compact protective storage case designed specifically for the UNI-T UT18C Voltage Tester.
This case protects the probes and display during transport and daily use while keeping the tester compact and easy to carry.

The design was created after my original tester probes started getting damaged in the tool bag.
It also helps prevent accidental bending of the probe tips and protects the front display/buttons from scratches.

Features

• Custom-fit for the UNI-T UT18C tester
• Probe protection during transport
• Compact and lightweight
• Easy slide-in / slide-out design
• Strong PETG-compatible geometry
• Optimized for fast printing
• Includes supports already prepared in the provided 3MF file

Printing Settings

Recommended Material

• PETG (recommended)
• PLA also works, but PETG is better for workshop and professional environments

Recommended Print Settings

• Layer height: 0.2 mm
• Walls: 3
• Infill: 15–20%
• Nozzle: 0.4 mm
• Supports: Required
• Brim: Optional

Supports are necessary for the internal overhangs.
The provided 3MF project already contains pre-configured supports, so you can simply open and print.

Printing Orientation

Print in the same orientation as provided in the 3MF file for best strength and clean internal surfaces.

Compatibility

Designed specifically for:

• UNI-T UT18C

It may also fit similar UNI-T testers with the same body dimensions, but compatibility is not guaranteed.

Assembly

No assembly required.
Simply slide the tester into the case.

Notes

This is a friction-fit protective cover.
Depending on your printer tolerances, you may need slight scaling adjustments (typically ±1–2%).

PETG is highly recommended because it offers:

• Better impact resistance
• Better heat resistance
• Longer lifespan in tool bags and vehicles
