Summary

Kingroon KP5L Y 9mm belt tensioner.

Hardware needed:

2 meters GT2 9mm belt (better aramidic fiber or kevlar);
GT2 9mm 20T pulley 5mm bore for stepper motor;
GT2 9mm 20T 4mm bore smooth (no teeths) idler pulley;
1x M4 x 30mm button head bolt;
or M5 x 30mm button head bolt for 5mm bore pulley;
1x M3 x 30mm button head bolt;
2x M5 20mm button head bolt.

Edit: due to difficult in finding an idler smooth pulley without teeth with a 4mm bore bearing, I've created also a kit for 9mm pulley with 5mm bore of the bearing.

It's quite a bolt on mod except the tensioner. 9mm belt pulls better the heavy bed making it capable of 5000 mm/s² acceleration during printing if coupled with a Nema17 42-48 or 42-60 motor rated for >2Ah.

No more than 3000 mm/s² acceleration for travel but the travel speed can be rised to 200mm/s if Y Jerk is set to 6-8.
