The model can be printed with no supports, and is not necessary to use glue, double sided tape or similar. All will fit perfectly.
The model is very compact and practice, it just need to be put on the printer. It fits perfectly with the hole and will not conflict with the glass or any internal operation.
See all the pictures, there will help you to assemble the kit.

Happy printing :)
