Replacement for Yaesu FT-290R bottom cover

prusaprinters

<p><strong>Motivation:</strong></p><p>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.</p><p>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.</p><p>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.</p><p><strong>Printer:</strong></p><p>Prusa i3 MK3</p><p><strong>Print Settings:</strong></p><p>0,15mm layer thickness, quality, support on build plate only, brim on.&nbsp;<br>PLA; PETG should be better due to higher temperature resistance.</p><p><strong>Orientation:</strong></p><p>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.</p><p><strong>Infill:</strong></p><p>Standard, the print consists of mostly perimeters due to the thin wall thickness.</p><p>How I designed this model:</p><p>I used FreeCAD 0.19.</p>
