Blind Puzzle Box - Easy Print Remix, with Inner Compartment

thingiverse

This is an updated take on Clarkerubber's outstanding Blind Puzzle Box Remix. I rebuilt it from scratch with some key changes to address issues I encountered while printing the original box, but unfortunately couldn't reproduce the excellent knurling texture on its exterior. Only the "B" version of Clarkerubber's design was remixed here. Note that the maze itself is mirrored in comparison to the original "B" layout. Some notable changes include: * This remix is larger, which may help resolve strength and tolerancing issues. * A lidded storage compartment has been added, partly to enhance stiffness at the guide pin so it wouldn't slip out, and partly to practice modeling and using threads. * The interior of the original was challenging to print due to steep overhangs on interior curves. This remix addresses this by modeling with a maximum overhang angle of 45°. * In the original model, the inner tube could be easily pulled free or pushed in with relatively low force. Everything is now more structurally sound in this remix. * The maze could be escaped once the inner tube was near the top simply by misaligning the two tubes. This has been fixed by adding an extension wall that lengthens the outer tube above the maze. * In the remix, the inner tube sits closer to the outer tube, resulting in less tolerance. To avoid problems with seams, two seam relief notches have been modeled on the inner tube. This should help the slicer choose a good seam location point. Note: The green partial models shown in the attached pictures were proof-of-concept only. Note that the orange print was also a prototype version of the maze. See the .stl renderings and actual files for more information. These parts should be printable by any printer capable of holding a 0.2 mm tolerance in a tolerance test. Many thanks to Clarkerubber for this fantastic idea, and others such as The_Fish who have remixed before me.
