Mechanical Files

  • The "frontpanel" folder has FreeCAD drawing which generate the DXF and other files for fabrication of the frontpanel, bottompanel and rear panel.
  • The "enclosure" folder has an OpenSCAD drawing of the Unit 1 enclosure. With in the folder is a folder "FreeCADAssy" which has a FreeCAD drawing using the A2plus work bench and duplicates roughly the Unit 1 assembly but which has the Unit 2 frontpanel, bottompanel and rear panel files.

Front Panel and Enclosure Folders Unit 2

Place holder for July-August 2023 Begin Construction of Unit 2.

  • Fabrication of Version 2 unit Frontpanel, Bottompanel and Rearpanel not by hand in house. ** DONE!**
  • The Frontpanel Version 2 has enlarged AC receiptical opehnings and will require reciptical cover plates. DONE!
