BXT-MTB-117 150mm AM bike

Finished the washers. Their thickness must be adjusted to the specific frame.
The preferred additional length of the tubes is from 0 to 0.2 mm.
In the drawings, I simply subtracted the additional width of the tubes from the thickness of the original washers.
I note that it is better to make the hole for the tube at least 0.5 mm larger than the outer diameter of the tube.
I drilled BOTH holes for the axles of the lower link to 17mm. And BOTH holes of the top link are up to 19mm.

An update to the problem of stuck suspension on bottom out:

On my size Medium frame, a 210x52.5mm shock does not get stuck at bottom out while a 210mmx 55mm shock jams in the bottom out position. At least one person reported that a size Large does not get stuck at bottom out while naeTech reports size Small gets stuck at bottom out at 52mm of shock stroke. The limited sample so far suggests that the problem gets worse as frames get smaller below size Large, but that's not confirmed.

I would still suggest that anyone with the frame test their bike by bottoming out the rear suspension with at a low air pressure in the shock to make sure the suspension does not jam at bottom out. Since the suspension is so progressive, you may need to reduce the air pressure in the shock to reach full bottom but you should have at least a small amount of air pressure to see the problem.

Just ride your bike and stop sweating the details.

We now have meter-deep snowdrifts and a 3D printer with a lathe standing idle... 
New printed link for small 200x50 shock. work but leverage go to linear...

NaeTech, this is an inspirational level of customization.  Very impressive!

A couple of questions:

• Your "washers" are similar to the part called "Pivot dust shield AL" on the Santa Cruz diagram, correct?
• Why do you want to use a 200mm shock when the frame is designed for a 210mm shock? Lower bottom bracket?

1) Original washers have more space for lubrication and a larger diameter than the bearing. And on the original links there are grease fittings that fill this system with lubricant without the need for disassembly! It makes sense to realize this beauty if you have links with grooves for large washers. But Chinese links do not have grooves and there is no place for it either. Therefore, I decided to use simple washers with a thin dust gap filled with lubricant - it will not allow moisture to easily reach the balls.

2) I just have an extra shock absorber of this size lying around “under the sofa” for a long time.

What material was that printed with? Is it just a plastic stand in for static (non-riding) testing before you make a metal version, or is it something you’ll be riding on?

This is PETG for size checking. If I decide to move forward, I will print from PA-CF20.
But what I see now makes me understand that petg does a good job - the plastic part can be made larger. For example:

@naeTech If you do decide to make it will you offer some for purchase?
