MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Unfortunately, it will be extremely hard to tell in my opinion without the switch joycons to test it.
What I did was I would try to put my joycon on it, take them off, sand, and basically keep testing till I had a decent amount of tension so the print didn't slide when I actually had a drink in it.
In the image provided I am pointing to the part you want to sand, but you will have to do both sides of the rail to get the best results.
