Want to modify a complex shaped plastic part; need a good, inexpensive, scan/service

[robosmith]

It's black plastic and shiny. Double whammy.

I tried coating it with flour and using the Makerbot digitizer again, after it failed with just a big glob the first time.

While the Makerbot digitizer produced something which looks similar to half of the original part, correcting the imperfections is still a large job.

Does anyone know of a service which can handle this job?

Mods: if this is the wrong place for this post, please move it.

What is it/can we see a pic?

Developer spray is normally the best thing to use for coating an object

It is a tray for my refrigerator ice/water dispenser. I'll post the pix when I get home.

Man you're better off designing it yourself. Seriously.
Put it on a sheet of paper with 5mm squares, trace the outline and measure a dozen points. These will serve you as a reference for a spline. The inside groove is probably just as simple to design.
I'm guessing it won't take more than 30 minutes.

well if you have to learn a cad package first - could take a bit longer than 30 mins. But yeah looking at it.
that's the route I'd go.

bit trickier in openscad, but easily doable.

Just put a sketch with a few measurements.

IME, your estimate is wildly over-optimistic. I've already spent more than 30 min and I have the rough shape from the Makerbot digitizer.

I'm using Sketchup, which does not seem to have a spline curve tool.

Doesn't anyone here know of a service which can scan this?

Take a pic of the item import into sketchup and trace it with the follow me tool.

Thanks for the suggestion. I've only used "follow me" to make a sphere (from a circle and a curve). It's not clear to me exactly how to use it as you describe.

Put here a sketch with key dimensions, I'll design it for you.
