I think this is in the right place. Please move if not.
It’s been mentioned a few times about making parts from a 3D printer. Making knobs doesn’t seen to work, but I was wondering about making feet. 3 out of the 4 feet on my Tech 465 scope have crumbled. All 3 have a white film. The good one doesn’t and is in good shape. I’ve heard others here say they have broken feet also. criageek showed us the stand he made from a 3D printer and got me thinking that it may be possible to do the same thing with feet. I would be willing to send off the good one to someone if they wanted to try. It looks like the originals were built in 2 pieces and glued together.
Here are two pictures of what I have.

should be able to make a mold from it, and cast some.

Seen this?

Walter Shawlee led the effort from the TekScopes forum.

Me, I used Hitachi cordwrap feet on the 475 I used to own.

Hi Freeman - Are those rigid or somewhat soft? I have some flexible filament that I've had good luck with, including a new foot for the Zenith Transoceanic I'm working on (upper left)

The thing that would make printing a new foot for you would be the overhang for the nipple on the end. One problem with 3D printing is that it requires a surface to lay the filament on. You can print this sort of thing using supports but they can be difficult to remove cleanly. Also, I don't know how well supports work with flexible filament.

Anyway, I'm willing to take a look and give it a try if you want to send me one ;) If you're interested let me know and I'll shoot you my address in a PM.

Rich

EDIT: I posted this before reading the previous post...that looks like it may be a good option if the price isn't too bad.

Hi Rich--Thanks for the offer, but I'm going to go with what Findm found. The originals are rigid and the fins are what break. The new ones have thicker fins which make then a ¼ " longer and they come with anti-skid pad which will screw on the bottom if you want to add them. A little pricey $10 each, but appear to be well made with better material. Right now the scope has to lean against the wall. It’s something when you think you’ve come up with a good idea and a member here will find where it has already been done.

Thanks Findm
Freeman

Here's a site you can have your own made.

https://www.shapeways.com/

You can upload a design of your own, design one from scratch with their assistance if you want it, or search the database and see if someone has already uploaded a file for what you need. If so, you just select what material you want it made out of, and then it'll be on the way to you.

I used them to get some replacement gears for my 90's cassette deck, turned out it was already in their database. $8 each for two dime-sized plastic gears. I was fine with that, they were otherwise unobtainable.

**Sorry, didn't notice this thread was a little aged.

Love those RCA boxes Rich

How about sharing the artwork here so I can make some too?
