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

thingiverse

So I've got this amazing Phil & Ted's stroller, but one thing is missing - cupholders! If you buy it straight from them, they throw in a small Starbucks-style holder that's super flimsy. I figured I could do better. I designed the upgrade in ABS, used 16mm and 8mm carbon fiber tubes for the frame and M3 helicoil inserts to support the bracket mount. All you need is four M3 helicoil inserts (2mm deep), a couple of M3 screws and a little pin of some sort. The pin slips into the original cupholder hole, keeping it propped open. Remove the pin and the holder folds down for easy storage! With a bottle in the holder, the pin stays securely in place. I added a long M3 screw so that even if things get bumpy, the ridges will catch on the hole and keep everything from falling out.
