Motivation:
I got hold of an old portable amateur radio Yaesu FT-290R, that suffered from leaking batteries. This was probably teh reason why the bottom cover, that is situated next to the leaking batteries, was missing.
So I designed a replacement of the part. I printed it using PLA, but I guess PETG would be better due to higher temperature stability when used portable in a car and in sunshine.
Since I needed a little more stability with the plastic instead of sheet metal, I added some stabilizers and feet on the outside. For shielding, I recommend copper tape on the inside, connected to ground.
Printer:
Prusa i3 MK3
Print Settings:
0,15mm layer thickness, quality, support on build plate only, brim on.
PLA; PETG should be better due to higher temperature resistance.
Orientation:
As in the model, on the edge, longest orientation vertical (!) to provide the stability for the thin areas. When oriented this way, the product is astonishingly stable.
Infill:
Standard, the print consists of mostly perimeters due to the thin wall thickness.
How I designed this model:
I used FreeCAD 0.19.
