Chevy Silverado cupholder insert 1998

A cupholder for my father in law's 1998 Chevy Silverado to replace the CD tray. I printed it in SUNLU HS Matte grey facing up with supports, but there's no reason why you couldn't flip it and print it, and if you've got your bridges dialed in you don't even need supports. The truck is super far away from me so I had to reverse engineer the dimensions from pictures, but my FIL says it fits perfectly. This is the only picture I have of it in the truck, because of this I couldn't be certain of the dimensions for snap-in tabs to lock it in place so I didn't make any; a suggestion is to use button-sized velcro on the underside. My FIL decided to keep it as is. I printed it dark grey thinking that's the colour of most truck's insides and then my FIL sends me pictures and it's light brown. Oh well, he's happy! I hope this makes other people as happy as it made my FIL. I've included the FreeCAD file so others can remix at will.
