strength and flight characteristics of the model depend on it.
Please follow the instructions of your 3D printer manufacturer
-
to avoid damage (maximum installation space, maximum
temperatures, material compatibility, etc.).
When handling sharp or hot tools, always take care of yourself
-
to avoid injury (wear protective clothing such as gloves or
goggles).
The handling of superglue and activator should only be done in
