For whatever reason I enjoy coffee from a cup without a lid. Of course, this is difficult when driving and I have come up with some solutions that scares anyone sitting in the passenger seat. This is why I came up with this.
I designed it for a 2008 Acura MDX cupholder, and am hoping the design is pretty universal. It has a hollow, tapered bottom half to sink into the cupholder and stabilizes with the built in tabs on my car. I notched out some pieces that allow a traditional coffee cup to be used, but found out after the fact that it is too thin for some of my cup handles. So far it has been able to handle some 90 degree turns, speed bumps, and general driving without issue.
Print was pretty straight forward. I designed it with rounded filets so that any printer should be able to print it without supports.
