Exactly what I was looking for, thank you very much! On my first print, I broke the free-standing part of the back and later also broke the frame from the base when I tried to removed the print from the print plate. Perhaps you have had similar experiences with your prints in "long-term operation". Reinforcing the rear panel and perhaps a chamfer between the base plate and frame would give this model the final touch. I printed it scaled down to 95 percent for a "flyer snug-fit".
