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.
