CAD Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below:

  • case
  • grid
  • strip-cover
  • back-cover

Build Volume

The parts require a 3D printer with a minimum build volume.
