Dual Z kit ender 3

I'm using a 620mm long T2.5 belt. The belt tensioner can be adapted to several lengths because you can move it on the gate and this changes the tensioning force. I think a belt between 610 and 630 should work. However I sized for 620mm.

For assembly you will need buy:

• M5x10 screws with T-nuts 10x
• M8x35 screw with M8 nut 1x (For fixing the tensioner pulley)
• Worm gear replacement kit (nut and screw) for ender 3
• Belt T2,5 620/6mm 
•  M5 grub screws 6X (for tightening the pulleys on the worms) 
• 608 bearing 3X (for top bearings and belt tensioner)
• 6000 bearing 1X (for bottom landing)

You also need to print the worm nut holder which I didn't draw myself. I used this model which works perfectly:

My tensioner is in 2 different colors because I finished a spool. It should be printed as solidly as possible, Minimum PETG at best PC.

Please share your creations or improvements

The kit can be removed in less than a minute by simply removing the belt and unscrewing the worm
