This is a golf tee caddy for up to ten golf tees. My golf tees have a diameter of 4.75mm and they are 7mm long. The Callaway logo is from Wikipedia https://en.wikipedia.org/wiki/File:Callaway_Golf_Company_logo.svg.
The design was made with Tinkercad. You can modify it if you wish. It's easy to remove the logo and replace it with another or your name. You can find the Tinkercad model here: https://www.tinkercad.com/things/haokkh8OXrS. Tinkercad allows to upload SVG files. With that, it's easy to use logos or other svg graphics.
The material is Black TPU (Tinmorry). I think PLA will work as well, but I like the flexibility for this project. For the logo I used an edding 750 paint marker, gold.
No supports, but I've added custom supports on the holder manually (Cura 5.0, Cylindric Custom Support).
