Created this for my mower. Printed it with 15% infill it is very stable. 
For "glas" i took regular "acrylic glass film". 

You have to cut the parts with slicer to the size of your printer.

After printing you have to glue them together with a good plastic glue. 

You can cover the cuts with “cover-clip” 

I used regular “superglue” which did work wonderful on “left” part. But on “right” part my glue got not dry and my model crashed. So i have no pictures of complete printed model but it works well and is very stable
