JoePKrcma's original Helmholtz brick remastered, remeshed and supported for printing

The internal mesh of Joe's published meshes are a source of trouble for 3D printing. I rebuilt it so the internal corners are well-behaved.

My remaster is a printable cleanup of Joe's original. It is intended to be exactly the same external shape, and the same internal shape minus the glitches.

I've included a 3mf file, two step files and an stl. 

“whatiprinted.3mf” is what I ran on my MK3S to give the photographed object. I printed thin and quick to check the supports.

“supported rebuilt brick.step” is the source of the mesh I printed with supports included

“rebuilt helmholtz brick.step” is the rebuilt brick isolated and posed upright

“rebuilt helmholtz brick.stl” is a mesh of the isolated brick
