4. Assembly Instructions

The model is designed in two pieces to avoid the need for supporting structures. This allows you to achieve a flawless printing surface with your finest printing profile.

A snap-fit structure is designed to help the two parts join together easily and precisely. Glue is not necessary for the assembly, but there is space for glue if you want to ensure a permanent joint.

If you printed with an older profile, the hooks might be thinner and easy to break. Please be gentle when assembling the two pieces. This issue has been fixed with the 2024/01/02 updated profile.

Additional notes:

If you don't have AMS for multicolor printing, you can remove the eye components from the printing profile. The model will still print fine, and you can then use a pen or marker to draw the eyes afterward.
