Phil and Teds Improved cupholder - 3inches for large water bottles

So I have this awesome phil & ted's stroller but the thing doesn't have cupholders!!! If you purchase it from them, you get a small starbucks type holder and it's pretty flimsy. So I decided to make a better one.

This is printed in ABS, I used 16mm and 8mm Carbon Fiber tubes for the frame and M3 helicoil inserts for the brace mount. You just need 4x m3 helicoil inserts (2mm deep), couple M3 screws and a pin of some sort. The pin slides through the hole of the original cupholder, it keeps it
