Back attachment only

I have removed the slots for top elastic since I don't find it very useful and to save on print time. Would just like to say what a good fit it is on the frames so well done to the original designer. I intend to make a version for thinner elastic when I have time. Print instructions I printed with a 0.4mm nozzle with 2 walls with a 0.6mm line width with the max volumetric speed at 7mm^3s^-1 in PLA and they seem to work well. Haven't included both sides, just mirror on x or y axis to get the right part.
