Building a simplified inexpensive <20 nanometer accurate vacuum-tolerant positioning stage for microscopy and lithography projects. Trying to unlock the caveman achievement by keeping tools/budgets necessary to replicate the work accessible for other hobbyists.

Also still working on a custom Slicer for a special metal printer design. The VTK library version needed replaced by a simpler Blender Geometry nodes solution to extract texture information, and infill hull features.

Also considered a beautiful solution to Roger Penrose's Andromeda paradox. That guy has a wicked sense of humor... very funny. =3
