My version of the rfBitBanger FreeCAD case.
-
Adjusted the size and location of the openings for the LED display and the RF filter modules to better fit my equipment. I thought the orginal openings were excessively large.
-
Changed the navigation buttons to triangular shapes to better indicate their function.
-
Changed the enter button to be a diamond shape.
-
Added a chamfer to one of the top cover bosses to provide clearance for an adjacent surface mount component.
-
Changed the top case recessed lettering to raised lettering and re-located the lettering to better suit my preference. Lettering location, font and size can be adjusted in the FreeCAD spreadsheet model item.
-
Call sign now included in the lettering. Call sign can be edited in the FreeCAD spreadsheet model item.
-
Recommend that the top case be printed with the lettering up to permit two color printing of the lettering.
-
Two color printing of the lettering is possible with a single color printer. For example CURA has a script you can use to permit a filament change at a specific layer. Instructions are a Google search away.
