This is my remix of mojode's fiamma awning rear cap. The original model would fit my awning but I thought I could give it a makeover and soften the edges.
Cheers to mojode for including the perimeter stl files so it was easy to check for fit.
I have also remixed the front awning cap here https://www.thingiverse.com/thing:3500078
Devel Design PETG
4 perimeters, 4 solid layers top/bottom. I sliced with Slic3r and had the first (up to height ~8mm) layers print with 0.1 resolution and the rest with 0.3.
Printed with the large face on the bed, set bed temp to 80 for the first layer and 60 for the rest so the overhanging edges wouldn't curl.
No supports needed, the retaining clips should print fine as I have included a bit of support in the model. May need a bit of postprocessing.
Hand sanded with waterproof sandpaper 400, 800, 1200, 1500, 2000 and 2500 grit to smoothen the edges, came out better than I expected!
Mounted fine except the lower two retaining clips (which I lazily cut off!), used a bit of silicone (pea size) to stick to the awning just in case the wind and/or thermal warping loosens the part and it takes off.
