3D printed closed loop timing belt - any good?

Let's find out if we can use 3D printed closed loop timing belts. I was testing with different designs, materials and also I tested these 3D printed belts from mechanical strength aspect too. ***Important update for 2.5.0 PrusaSlicer users: Print Settings / Layers and perimeters / Perimeter generator: turn from Arachne to Classic. And turn off Fill gaps. Cura users: Sorry, new 5.x currently don't want to print those two lines continuously. Can't find the solution so far, except to use older 4.x version.
