Friday Night Lights, Cold Bleachers, and Nowhere to Put Your Phone

Picture the bleachers in October. It's colder than you dressed for. You've got a coffee in one hand and a kid's water bottle in the other. Your phone is somewhere in your coat pocket, and you know that the second something good happens on that field, you'll be doing the frantic pocket dig while everyone around you gets the video.
That's the entire origin story of the football wristlet. There was no grand design process. I was annoyed, and I have a 3D printer.
Why pockets don't work on game day
Coat pockets are a trap. They're deep, they're full of gloves and receipts, and half of them are the kind that dump everything out when you sit down on a metal bench.
A wristlet solves it by never letting the phone leave you. It loops around your wrist, so the phone hangs there ready. You can carry a coffee and still have your phone in the same hand. When the play happens, you're already holding the camera.
It sounds like a small thing. It stops being a small thing around the fourth time you miss a touchdown because you were digging through a pocket.
The part I'm genuinely proud of
It comes off the printer already assembled.
No glue. No clips. No little connector piece that rolls under the couch while a toddler "helps." The links print already interlocked, so you pull it off the build plate and it moves.
That's called print-in-place, and it is far harder to design than it looks, because you're not really designing the plastic — you're designing the gaps. Too tight and the whole thing fuses into a solid lump. Too loose and it prints as a pile of parts. There's a narrow window where it works, and finding it is a lot of failed prints.
When I posted the football one, that was the thing people latched onto. Not the shape. The fact that it came out finished.
Team colors, without the licensing weirdness
The nice thing about printing your own is that you're not waiting for someone to stock your team's colors. You pick two colors, you print it, done. Nobody has to sell enough of them to make it worth manufacturing.
I've done a lot of these in school colors for people, and it's consistently the request I get most in the fall. If you're printing it yourself, a color change at the right layer gets you a two-tone one without needing a multi-material setup at all — just watch for the layer change and swap the spool.
It's not really about football
I named it after football because that's the season, but the same thing has gone to volleyball tournaments, all-day baseball weekends, and one very long soccer game in the rain. It's the same problem every time: you're outside, your hands are full, and you need the phone accessible without holding it.
The sports versions exist because that's when people asked for them. The actual use case is "I have too much to carry," which is most days.
Print it or buy it
If you have a printer, the football wristlet files are a 3MF with the print settings already in them, so you're not guessing at tolerances on the moving parts. That matters more here than on most models — print-in-place lives and dies on getting the clearances right, and those are exactly the settings that don't survive being exported to a plain STL.
If you don't have a printer, I'll print it for you in whatever two colors you want.
Either way, you get the version that works, because I already printed the versions that didn't.
Whose colors should I print next? Drop the team in the comments — I keep a running list and I do actually work through it. 🏈
