How to exactly duplicate rubber parts? Answered

i have a few old sets of unusual mountainboard trucks and spare parts all made by a company that went under about 13 years ago so no chance of getting new parts, all the parts are used but usable except for small rubber non ribbed gaiters/seals that have cracked and split except for most of the ones on the complete trucks. is there somewhere i could take one of the surviving rubber bits to have it duplicated as inexpensively as possible or is there some other method of duplicating them exactly?

Edit: I'm in the UK

who could probably solve your problem for a price.

One offs tend to be expensive However.

Perhaps You could mould a replacement from Sugru?

apologies, totally forgot about location, yes im in the UK too. i probably will need about 20 pieces to replace all the old parts and have a spare set so fingers crossed that won't clean out my bank account.

i've briefly used sugru for rough repairs but im not sure how to mould with it, the parts need to be as exact as possible to maintain a perfect seal on either end against water going in and lubricant coming out and i don't trust the steadiness of my hands haha...

You could make a mould from plaster of Paris fairly easily from the existing parts then squash the Sugru into that to get a fairly goof copy.

3D printing in flexible filament if you know how to?

i thought about this but thought 3D printers only did hard plastic stuff, would this flexible filament stuff result in a duplicate hard wearing but flexible enough to survive a constant but mild twisting/bending motion? the big end in the cap is attached to the motionless part of the truck while the small end fits over the axle so it needs to be able to survive days of the axle pivoting to steer...
