RTIC Coffee Mug Insert For Camper

I designed this to keep our coffee mugs from rolling/sliding around in our camper while traveling down the road. It's specifically designed for RTIC coffee mugs and fits perfectly on the shelf in our 2020 Braxton Creek Bushwhacker teardrop camp trailer. There might be exactly one other person on here that could use this so I figured I'd put it out there. I recommend ASA but PLA+ or PETG should work if you're not in a super hot area or keep your trailer inside somewhere. This is my very first design ever using CAD so it's not fancy and doesn't make the best use of space or even attempt to save fillament so be aware that it's a bit expensive for a print considering it's mostly a solid block with some cut outs. I've attached the .stl so you can change it however you want if you just want to use this for anything else that's not this one super niche need.
