This Thing includes all relevant files for printing in .STL form, as well as 3 assemblies in .STL format; a full assembly showing the exterior of the model, a semi-complete assembly showing the interior of the model, and an expanded assembly illustrating all pieces contained in the model.

This Thing also includes all relevant files in .SLDPRT form for easy modification for your specific materials and requirements. Specific sizing for springs, dowels and magnets will not be provided, as I found that it was very difficult to find exact sizing that worked consistently.
