3D printing parts

Postby find_bruce » Fri May 25, 2018 3:11 pm

I have been inspired by Quang's efforts on bar plugs, tube stem cap & stem caps, I was thinking about what other hard to find parts are amenable to 3d printing.

I have picked up a trashy paid of 105SC brake levers - the scratches were reasonably easily removed, with enough elbow grease they will polish up nicely. Its a good opportunity to practice my sanding polishing skills (there is a pair of 1055 brakes in similar condition)

What won't polish up however are the plastic bracket caps (item 3 on the exploded view) - one is missing and the other is badly scratched. The side with the missing cap is also missing the small plastic washers on either side of the wire hook unit (item 4 on the EV)

The hoods were also perished, however they are available new as shimano still make these levers as [url]BL-R400[/url] and so the hoods can be had for €4.19 + shipping so I will throw a pair in with my next order. Yes I could just but BL-400 levers for €24.33, but where's the fun in that.

Any comments on whether these can be 3d printed & how I would go about designing & printing them?

Probably can be printed, although it may not work out so well. The part is quite thin and will need to be clipped onto the rectangular lug sticking out from the lever body, so there's a good chance that the part will crack.

Nothing stopping you from trying though. Onshape, TinkerCad and plenty of other online CAD programs are available along with lots of tutorials on Youtube.

exciting opportunities with printing at

The design phase is more challenging for 3D parts.

I might look at doing a reproduction headbadge for the Blue Riband. Whilst it is detailed, it can be designed in a 2D space (Photoshop) and then interpreted in Shapeways 3D app for printing. Would be printed, then cast in brass.
