Toyota Tacoma leaf spring silencer

Silencers for the leaf springs in a tacoma, however they'll likely work in most other leaf spring setups that have a 12.5mm (1/2") bore.

I printed these in solid PETG - forums show people making these out of UHMW, waxed fabrics, urethane, etc. I think ASA/ABS would be ideal, but I'd also be curious to see how well these come out in TPU. Regardless, this is a very high load part and MUST BE PRINTED AT 100%. I lubricated them with spray on dry silicone grease, however they were silent with no grease as well.

I have a thread on ayyws documenting the longevity of these parts: https://forum.ayyws.com/showthread.php?tid=27
I will update this as time goes on, however most importantly the springs are now silent and the part is cheap to make
