Vendors that let you specify TPE Insert size?

[Jumbojaw]

Hello,
just recently got my first doll, a WMDoll 140 with replaceable vagina.
Got an extra insert just in case, so I ended up with 3 in total. Their hole diameters are 0.5, 0.9 and 1.5cm respectively. Unfortunately this is too small, I can kind of squeeze into the largest one with plenty lube (and while it's not inside the doll), but it's not exactly pleasant and for the two smaller ones there's just no way in hell.

Doing my own modifications with soldering irons and making incisions in the existing inserts seems complicated, and I'm a total beginner.

So now I'm looking for trusted vendors that let you specify the opening diameter of the TPE insert during ordering. ~2.5cm would seem about right. Just looking to get new inserts, the doll is fine.
Any suggestions for good sites with this kind of feature/large selection?

Bonus: A vendor in europe
Ultra Super Bonus: can select color, make it fit WMDoll Tan skin

You can order more inserts. Or do what i did and modify flesh lights and strokers. They tend to feel better anyway. But you will need to rubber band the end or plug it somehow.
