Hi the slip clutch from my Torqeedo outboard shattered the other day. Took it to dealer in Southampton.. no longer available. They suggested getting a new one 3D printed. Does anyone know of a service where a complex object can be copied and reproduced in small numbers for reasonable cost ? I found one chap who said he could do it but not until next month, in PETg ?
Thanks in advance

Hi Rory,
I design and print high quality stuff in various materials. Would be happy to draw it up and produce it for you. I do PLA, PETG, ABS, Nylon, Carbon filled etc. All I would need is either accurate dimensions or the item itself. Call me if you like on 07855 429922. I'm also a yachtie so I've a good idea of what will last and what won't. I would suggest Nylon might be the best. Wouldn't use PETG for wear. Turnaround would be a couple of days. Regards
Andrew Holder

What is the material? This is critical to know; too slippery won't work. My other concern is that 3D printing is generally slightly weaker, because of tiny voids, and there is no obvious way to compensate for that. Perhaps this is not important, if it was a one-time impact.

Molding could be another option, depending on the material. The shape is simple enough and fiber could be added to make it stronger.

Good luck. This is a growing area.

It’s a sacrificial part along with the shear/cotter pin designed to save the prop and the motor. I don’t want it too strong.

But you also don’t want it too weak! If those “castellations” are load bearing its worth being aware when trying to print as probably the default way to print that shape would have the weak layer directions under shear - which is the weakest direction. Many prints are not solid (100%fill) which will be weaker too. A machine shop could easily copy it in solid delrin or nylon for probably same cost as printing at 100% fill.

Cheapest diy solution with no tools probably to use the old part to make a mould (using the sort of silicone used for dental impressions) and then casting in a suitable polymer.

I've put a trial one in the post just to check dimensions. I'll send more in nylon, carbon filled PETG and ABS to see if they work.
