9A5N Solid State CW Paddle Travel Case (No Supports)

This is a simple, durable travel case for the 9A5N Solid State CW Paddle.

The design is a two-part system:

- Inner carrier that securely holds the paddle and protects the plug/blade area

- Outer sleeve that slides over the carrier for transport protection

Both parts are designed to print cleanly with no supports. I printed this in PETG on a Prusa MK3S with a deliberately snug fit. Because printer tolerances vary, STEP files are included so you can easily adjust clearances if needed.

Retention note:

The sleeve uses a snug slide fit with small locating nubs. For “thrown in a bag” use, I recommend a simple retention method:

- A thick rubber band or cargo-style elastic around the sleeve (lowest bulk, very reliable), or

- A small Velcro strap if preferred

This approach keeps the design simple, robust, and easy to customise.

This is a protective carry case, not a crushproof enclosure.

Print settings used:

Material:

- PETG recommended

- PLA is fine for light-duty use

Layer height:

- 3

Top / bottom layers:

- 5

Infill:

- 15–25% (grid or gyroid)

If the sleeve fit is too tight on your printer:

- Apply +0.1 to +0.25 mm XY compensation / horizontal expansion, or

- Scale the outer sleeve only to ~100.3–100.7%, or

- Adjust clearance directly in the STEP file.
