For a very quick print, I've tested this model with 0.2mm layer height, 2 walls, 2 top/bottom layers, 5% infill only. The result is in the pictures.

From my point of view works good, but I would print the lid (butt) with more top layers (4 maybe) and 3 walls. Maybe even go lower on layer height.

The two main parts easily connect to each other, printed without any support.

The penis part can be used to easily open the lid (pull up :) ). This small part, could use a bit of support on some printers, but for me it worked ok on Bambu.

If you don't want the penis part, please print the lid without the hole for penis attachment.

Please share your print if you do it.
