My wife likes her starbucks refreshers. They don't make plugs for the Trenta size, and they are so sticky when they spill in the car. I designed this for her and she loves it.
I printed them from TPU with a .8mm nozzle at 20mm/s on my Neptune 4 Pro, 2 walls, 50% infill, layer height .2mm, but I'm sure they'd work with smaller nozzles and out of PLA or anything else. They took about 8 minutes to print
There's a small lanyard hole so they can be attached to a keychain or just a loop to hang on your turn signal lever so you don't lose them.
v5 is made to print vertically. V7 can be printed laying down. Neither need support as I printed them. YMMV
