3D Printing in TPU wanted

[Uncle Bulgaria]

With Alan Bain and factory's help I've got a 3D file of the Tektronix 2445 feet, which on my 'scope are crumbling. The maker suggests TPU as a semi-rubbery approximation to the original.

Assuming someone round here has a suitable 3D printer, is anyone willing and able to flex their muscles and print me a couple? I know I can get some done by a commercial outfit, but I thought I'd ask here first. I'm willing to pay, of course.

Although I was given a 3D printer recently, I've yet to get everything 'up & running', so I can't offer to make them for you. I did wonder though, could JLCPCB maybe be an option ? They make excellent, and low cost, pcb's from a set of gerbers, and I know they now also offer 3D printing to order (JLC3DP), probably also to a very high quality ?

Just a thought anyway,
Alan

Happy to help - PM me. I currently have Blue and Grey TPU rolls.

Thank you both - Goldie99, I am uneasy about the very cheap prices offered by these circuit houses (I read this Eurocircuits post a while back and try to do my bit), but thank you for the suggestion. When you see the result I think you'll be enthused to set up your printer!

In the event, ScottishColin has done a sterling job. I've attached some pictures for future reference. The back plate comes off to remove the feet. The only real difference is that the originals had metal inserts moulded in, so I've put a washer under the heads of the four rear screws to spread the force. Additionally there's a screw that goes into a threaded insert from the back in the centre of each foot. However, it doesn't feel flimsy without this screw, and if it does I'll try a self-tapper in its place.

I'm amazed at the capability of the printing and very grateful for the speed and generosity of ScottishColin who's printed these for me. What a nice bunch of decent people congregate around here.

They look very nice, think I prefer the grey to the originals too.
If you want the pictures to remain on the forum for future reference, you should post them in the workshop/test gear section, anything posted in the parts wanted is only available temporarily before periodic deletion.

Of course; good idea. Yes, the grey is in the same sort of area as the Tektronix colour so doesn't look at all bad. The material is noticeably more flexible than the frangible originals. The front ones must be made of something else as they don't appear to be suffering the same deterioration.

I'm pleased they fit so well. And having seen it, grey was a better choice that slightly sparkly blue.....
