Hope have published a really comprehensive guide to fitting and maintaining their brakes.
It includes a link to files for 3D printing various bleed/spacing/set up blocks which is really cool, Â But I don't have access to a 3D printer and I've not needed to get any stuff done before.
What's the best way to get some printed (or will somebody on here do them for me for cash?)

[interesting that Hope still recommend lubing pistons whereas someone was claiming on here recently that you shouldn't as it's the friction of the seal on the piston that they need to retract properly)
There's a few people offering them on eBay for not much money. If you're stuck, or want what I think is a better design for popping pistons out of E4s, PM me.
Thanks - I should have checked there. Â Photoprints92 seem to be doing them at decent quality and price
Stuck one each of the V4 ones in the slicer and it reckons 72g at the recommended 70% infill so about a quid's worth of PETG. I've only got blue filament but happy to print you off a set and post, you make a donation to my local food bank?
There's some low quality garbage ones on eBay, avoid ricbuc76 if he's still knocking them out, terrible dog rough pos items, I totally recommend dench69, superb quality.
Just be aware if you do get one on eBay to check the seller feedback as I had somebody selling dodgy 3D prints at a high price (he had reduced the amount of fill to virtually nothing)
Had to get eBay to step in at the end as he was a real chancer
Another seller printed them to exactly how hope said
Finally got around to fitting these brakes and using the 3d printed Hope tools. Well worth the money - I've always budged a bleed block (usually something from the SRAM kit that almost fits) on Hope in the past but a purpose made block is better.
The alignment guide are excellent though - it's always been an awkward job trying to sight the gaps from various angles and the metal Brizman shim I bought a few years back didn't seem to help but with this it becomes a job that takes seconds. Â loosen bolts, drop on block, give it a shake to ensure its settled, tighten bolts.
The Hope bleed kit (pot that sits on lever and a hose adaptor that stays sat on the bleed nipple) also worth the money. Â much less Dot fluid on the floor than any time I've bled hope before - *almost* as clean as a SRAM bleed with good syringes.
