Secret Shelf with Lego compatible Brick things

I Liked the Idea of a secret shelf, but I wanted to Put some Lego on it.
So I added a Lego Plate on Top.

Printing:
Printed the Top side (Lego_Regal) with the topside down. This saves on Filament, but does alter the Surface on the Top.

Post Printing.
Some sanding is required, I did not change the tolerances on the original Model, so keep that in Mind!

I Printed it as a gift in Prusa Silver PLA. PETG might be better, but I have no Experience with this Material.
Printed on the Prusa MK3S+
