This is a modular version of my priming tool.

Printing in .24mm layer height without support worked fine for me.

Print the spraytool_grip (or use the one you might have already printed from v1, it's the same).

Print the spraytool_gripstick and slide it into the grip. You can secure it with screws, but it shouldn't be neccessary.

Print more stick parts and attach them.

Print 1 spraytool_thumbwheel (or use the one you printed vor v1)

Print transferwheels as needed (again, same size as v1)

Print spraywheels and adapters as needed (you can use the v1 spraywheels, too).

Use rubberbands to attach your models, or directly stick them to the wheels.

I used the Camera Handle Pistol Grip by blu06 with some adjustments for this.
