Printing & Assembly Instructions

Ckeck the attached pdf for detailed instructions.

Printing Tips:

• The streets require significant support structures. To make removal easier, I’ve slightly raised them above the plate. You can lower them if you want to save support material, but removal will be more difficult.
• For a glossy finish, reduce the print speed of the outer walls significantly. (These settings are already included in my print profile.) I used Bambu Silk+ Filament for that.
