I've just found some thermoplastic polyurethane filament that fits My nephew's printer and will stretch 3 times it's original length.
Available in Black, Blue, Red, Yellow, Clear and Orange. Fancy an Orange relay bracket? Black PP would be good for indicator brackets.

TPU is allegedly difficult to print with, after quite a bit of investigation I bought a small spool to experiment with.

Can you 3d print in rubber? I thought the front indicator mount issue had been resolved with 3d printing and that makes sense.y

TPU is ‘rubber-like’

Unlikely that the brackets are rubber anyway, probably neoprene? Darren, who is printing the indicator brackets and where is the 3D model?

Can someone send me a sketch of an original with accurate measurements?
It'll take about ten minutes to create a CAD model of such a simple object. |

Ben sent me a sketch with dimensions and I made a CAD model
I printed that in PLA (regular plastic) which is a known substance and gives good results If printing in TPU doesn’t work it can be used to make a mould I then printed it in TPU It’s in the post to Ben to see if it fits and is flexible enough to use Last edited by slob; 10-02-2024 at 11:31 AM.. |

I like that a lot.
Are you using PLA for the support and cutting it off? Do you use PLA for support with the TPU as well? I recently bought some water soluble PVA to use as a thin boundary layer between the support and print. Not sure if it works yet, but a thin layer is all it's getting as it's rather expensive as filaments go. Have you any idea where I could find the toxicity of the various filaments when printing? (ie when hot.) Trying to come up with an extraction system for my nephew's printer that doesn't also suck all the heat out.

nothing i’m using so far is too smelly, the pla is meant to be ‘food safe’ once cooled, eg you could make cookie cutters etc from it.
you’d want extraction for something like abs which is both hotter and smellier. check out https://www.tukkari.com/ for enclosures with filtration i only have a single extruder printer, so the support is the same material as the part in each case. it basically tears off with a little help from a blade as it is very lightly attached.

The finished result looks amazing from my crappy hand drawn sketch!
Now makes me wonder if those super expensive inlet rubbers I've just paid nearly £50 for could also have been printed!
