About this 3D model
Minecraft Twisting Shulker BoxI designed this in Fusion 360 using coils and sweeps to make the 'threads' for the box. The threads have about a 0.2mm tolerance so they won't need any working in after printing, they simply slide together! The outer walls are quite thin but just handle with care and don't rip them of of your bed with too much force like I did. The overall model is 50mm x 50mm x 50mm and the cavity inside has a height of 46mm and a diameter of 26.7mm so it is good to hide little gifts/sweets/candy inside.
