Sovol SV06 X Axis Tensioner Block

Update 12/24/23

If I helped you, leave a review, make, or a heart…c'mon people….I don't upload for myself…

I have added my newest version of the block with a step file to remix to your liking.  The long version is for those who have shortened their belts, which I forgot to mention.  You can remix the long version or just use the original if you want.  

So when my X axis tensioner broke, it was of course in the middle of an important print.  I got massive layer shift and a big surprise first thing in the morning.

I pulled the tensioner out, and it was really bad. I made this so I could have a stronger part.  It has holes for m4 nuts instead of press fit brass inserts.  The walls are slightly thicker and the area in front of the pulley is lengthened to provide more strength for the m4 nut.

Pictured is 2 of my parts with the original broken block.  The pulley is a slightly tighter fit, but it turns freely.  Don't overtighten the pulley screw.  

You will have to use the tensioner knob to cut threads on each of the 2 screw holes or a slightly oversized drill bit if you want the screw to drop in.  Make sure you have a steady hand and an eye for level if you hand thread it.  You can run the screw through the nut first if you don't want to ruin the alignment by hand.  I am not sure if that cuts the threads in reverse though.

2 M4 nuts needed.  

Print lengthwise.  I used Carbon Fiber ABS 0.6 nozzle 0.2 layer height, 7 perimeter walls, 253c 105c bed, 50mm/s on an ender 3 v2 neo.  printed without an enclosure but with a brim.

The original is included along with a new longer version that allows for more adjustment when you have to cut your belt.  The longer model is for those who need to trim, or have trimmed, their belt.
