Cup / Mug Holder for boats or cars.

thingiverse

I drink tea and coffee, and have a collection of mugs - of varying sizes - but I also grab sodas and the occasional Styrofoam cup of joe as well. My car's cup holder was not so accommodating. This cup holder was designed quickly to fit any size of mug or cup, regardless if they have a handle, are oddly large, or even if they're rather small. Print it out, put the inset inside, and depending on the orientation of the inset, it can hold cups from small to large with ease. For the largest of steins or liters of soda - simply remove the inset. For boat use, attach some of the tacky foam no-slip pads to the underside of the base. It'll keep your drink secure. In my car, a touch of Velcro on the base keeps it stuck to the carpet. Enjoy! Instructions I printed mine in PLA - works great. It's ugly and simple - but I really grew to appreciate it's function.
