10mm Straw Cap for Stanley & Copy Cat 40oz Tumblers

My wife's church group recently had 40oz tumblers made with the groups name and insignia on them.  I thought it would be helpful to print TPU caps for the entire group.

I printed the first batch in Overature blue 95a TPU, and those are what she handed out at church yesterday.  

Since I have two open spools of TPU, the blue Overature and some green Priline 98a TPU, I thought I'd like to see how the model looked in two colors, so I printed her a bare cap in blue, then printed the cross atop the cap in green.  My wife liked it well enough that I'll be printing these things in two colors so she'll have enough of them to hand out next Sunday.

All of my machines are super low budget “sub $200” single material machines, mostly altered to a state to where they're barely recognizable as the machines I'd purchased.  I printed these on my Tronxy XY-2 Pro using a Creality Sprite Pro extruder.  I know slicers have improved in recent years to include provisions for material swaps for multi color prints on a single extruder machine, but I'm often slow at adopting new tricks, so I split this into two pieces to use my old method for multi-color prints.  I seldom publish G-code with my models, but I included the G-code for the two prints that make the whole in two colors for “REFERENCE ONLY”.  Unless the machine you'll print these on is configured similarly to my Tronxy, the G-code probably won't play nice on your machine.

The cap portion of this model works nicely in both 95a and 98a TPU.  I've printed both materials on dual gear Bowden machines in the past, but to be honest, I've never been happy with retractions and stringing, especially when running 95a through a Bowden setup, however, the more rigid 98a does print decent on a dual gear Bowden extruder machine.  If you're printing in 95a or softer, it's probably best to make these on a direct drive machine of some type.

The base model comes in two variants, one with the cross, and one bare.  The bare cap can be used as is, or one could add other types of logo's etc.

These caps are intended to be printed in TPU and it's doubtful they'll work in any other material, unless of course you applied heat to the model printed in a rigid, yet somewhat impact resistant material like PETG, so that it's in the shape it would need to be for application to a straw.

I'd like to thank my friend TravisT, who twisted my arm hard enough that I finally cracked open my first spool of TPU just a few short months ago, a material I've had many hours of fun with since he had me try it.  https://www.printables.com/@TravisT_1216398
