Renaissance castle box — inspired by Rosenborg, the whole castle lifts off a hidden tray

A Dutch Renaissance castle, 240 × 108 × 250 mm, that is a box. The entire castle — brick walls, sandstone trim, copper-green roofs, three spired towers and the stair tower — is one four-colour print that lifts off a plain tray hidden inside it. Lift the castle and the tray stays on the table.

Read before you print

It is not a 1:1 replica. The castle is inspired by Rosenborg Castle in Copenhagen, not a measured model of it. Proportions, window rhythm, towers, gables and sculpture are simplified and adapted to a 0.4 mm nozzle and to the box, and many details differ from the real building. Treat it as a castle of that era, after Rosenborg.

It takes almost three days to print in colour. The four-colour castle slices to 2 d 23 h 46 min and about 1.1 kg with a four-slot automatic filament changer, colour changes and prime tower included. The tray adds 2 h 12 min. Check you have the spools, and the time, before starting.
