Simplest Parametric Cup Holder Adapter

I was looking for a cup adapter for my water bottle, but other models didn’t fit, and the parametric ones were too complicated. So I made my own. With only six different settings, it’s easy to get a custom fit for your bottle and your car. IMPORTANT: Measure as accurately as possible, but always add the tolerances listed below. I printed this in PLA and have tested it only up to 90-degree days (with even higher temperatures inside the car). Some shrinkage occurred, which is why I recommend adding 3–4 mm to the cup diameter. If you want a stronger print, you can increase the wall count or infill or use a more heat-resistant material. To explain each parameter, I made a simple bullet-point list:Cup Diameter – The bottom of your cup’s diameter (add 3–4 mm for heat shrinkage and tolerance).Top Height – The height of the adapter holding your water bottle. I recommend at least 30 mm for securely holding your bottle.Bottom Diameter – The diameter of the bottom of your cup holder (subtract 2 m
