Safety notes

Insert insertion

When inserting M3 inserts, always work over a flat, solid surface. Never push an insert above a hand or body part. Injury can occur if the tool slips.

Recommended workflow:

1. Clean the entry with tissue forceps.

2. Start the insert gently by hand.

3. Drive it straight with the 2.5 mm T-handle ball-end hex key.

Soldering

Soldering is required for the screen and IR nosepoke / IR barrier assemblies. This may limit use by builders without soldering equipment or experience.

Plexiglass

Do not clean laser-cut plexiglass with alcohol. Alcohol can infiltrate laser-cut microcracks and cause later cracking.

The matte side should face inward to reduce reflections unless a module-specific exception is documented.
