(Yet another) Sunvisor Glasses Holder, but designed for ABS/ASA printing

It is just a sunvisor clip for a pair (or two) of sunglasses. The thing about it is that it was designed to be printed in high warp materials, such as pure ABS/ASA/PA/PC, using a thermal expansion grid on the bottom for controlled material contraction and a chamfer in order to all but eliminate the elephant's foot. 

It should print as-is on basically any printer, without brims, rafts or draft shields. I designed, tested and printed mine on a Lack enclosed Sovol SV06 and in the 15 minutes it took to print it in ASA, the chamber barely got up to 30C. As for layer adhesion, I can't break it with bare hands, so I guess it's good enough?! 

It will obviously print in PLA, PETG or any other material, but a car's interior temperature in the summer WILL deform lower temp materials. Also, I wouldn't trust HT-PLA for this job.
