Bolted Soma

This CAD model was designed by Oskar van Deventer, copyright (c), 20 February 2025

Bolted Soma is a puzzle challenge for which you do not need the physical puzzle object.
-Go and sit at a comfortable place.
-Read this message in full.
-Close your eyes.
-Solve the puzzle, without opening you eyes.
Bolted Soma has the regular seven Soma pieces, and nine bolts that are three units long. The Soma pieces have threaded holes through all cubies in all directions. The goal is to assemble the Soma Cube and insert all nine bolts. However, there is a special requirement: one can separate the Bolted Soma in two parts without unscrewing any bolts.
Did you succeed? How long did it take you?
