Cupholder adaptor for mugs with handles

My favorite mugs are large, awkwardly shaped, or have a handle that juts out. That makes it impossible to store them in the cupholders on my recliner chair. This adaptor fits into the cupholder and provides a flat, larger surface for the mug, with a cutout for the handle.

I printed the two pieces separately without supports and then glued the two flat sides together. The insert for the cupholder is 90mm in diameter. 

Printed in PETG (so it can withstand hot liquids) at .2mm on Prusa Mini+.
