Interesting modification. I'd be very hesitant to trust that 3D-printed adapter, though. What is it made of?

Not sure of the exact material but I'm not concerned as it's only damping forces it's dealing with which, on a fork, are fairly low compared to if it was the spring side. I've had 3D parts made previously which have stood up to some fairly significant forces trying to pull them apart, and certainly far in excess of what this will be dealing with.

I remember the elastomer stack from my Quadra 21's firing into my chest under compression when the plastic threads on the topcap just gave up. Hopefully that won't happen to you!

Ahh, the mighty Quadra with early plastic. Perfection. Thing is, I get the concern, after all it's 'just plastic' but lots of forks have had plastic top caps over the years, even single sided 'modern' ones like the X-Vert Carbon which essentially had similar spring and damping rates to this 888, and not had issues. And that's spring side where the bottom out force with 50lb/in is 350lb, or 180kg (ish). In contrast damper side forces are pretty low even in rebound so it'll be absolutely fine. Bits like this have been fitted to numerous World Cup bikes over the years with zero issues. Even basic PLA has more than enough tensile strength with threads this size.
