I want to share this nice Box from SUNSHINE (https://cults3d.com/de/modell-3d/haus/print-in-place-spring-loaded-box)

Its possible to print it in place without any Support or brim. Try my profile out and let me know if its works with your printer as well.

Just to inform you before you print:
The joke about the box is to achieve as good results as possible without support. For sure you can achieve better results with support.
