**Not that it is applicable to you, but I was really surprised when I
visited my local public library last year, only to find that they had a
high end 3D printer available for use by those who held a (free) library
card. It may not suit you, but it would be likely cost-effective.

I think you will find it hard to get a budget 3D scanner and 3D
printer to make acceptable knobs with any type of fine detail. Or fine
finishes for that matter. Some folks print stuff using ABS and then
polish the stuff in an acetone vapor chamber of some sort. That can
work pretty well. But still the best resolution of inexpensive
printers is ends up to be, in a practical sense, about .25mm, or .010\"
at the finest. The cheapest 3D scanners that will scan stuff to a
resolution of .1mm, or .004\" start at about 700 bucks.

That reference sounds a bit highbrow and literary ... I know
it as the \"Oozlum Bird\" from the UK \"Carry On Up The Jungle\"
film :)

We have the Ooh-Ahh bird - a one-pound bird that lays a two-pound egg. Some say a square egg - but we all know that is anatomically impossible!

Maybe it got confused with the square peg?

I\'m only familiar with the hot plastic style of 3D printer. They have them at the local library and before COVID I was able to watch them build some impressive sculptures (with kids working on them.)

I did not realize there was another kind with higher resolution available until I saw an ad for 3D printed trumpet mouthpieces, and the required finish and resolution is much higher, so they are using a cured resin approach.

Yes, it\'s CAD, but the approach is a little different. Where I think of drawing as an additive process, the approach here seems to be start with a larger shape and subtract elements.

I built a resin printer using a projector and CD/DVD drive from an old PC. Resin is stinky and requires a space with vents and fans. It can get messy. Results or \"ok\". The price of these machines continues to drop and I\'ll probably end up grabbing a decent one soon.

I\'ve used tinkercad.com to create a few items. It can get bogged down but it\'s a great site.

Netfabb is a must have. It fixes any issues with your objects after creation. It\'s free and helpful. https://service.netfabb.com/

I wasn\'t even thinking of the resin printers. They can generally print
at a higher resolution than filament printers. They are limited though
to just several resin compounds. Filament printers have, as of now,
many more options. For printing small stuff like knobs a small resin
printer might just be the ticket. And you can get small ones for about
200 bucks. Which leaves more money for the scanner. Maybe Pete doesn\'t
even need a scanner with high resolution. He could scan at the low
resolution and then clean up the scan with a CAD program. That would
work. I have done similar stuff converting jpeg files into CAD files.

Hiya,

If Pete decided resin was the way to go I would highly recommend Anycubic Photon for about $200 or the ANYCUBIC Photon S which has \"dual rails\" for a bit more, $400 or less. Anycubic has a huge following on facebook and I\'ve been following them for a few years. Everyone there is extremely nice and the information they provide is invaluable. I might grab the Photon S next year. The Build volume : 115 x 65 x 165 mm.

Creality has a huge following on Facebook and support can be found in a lot of places. You can find parts for it in many places if required.
Creality Ender 3 for about $200. Nice build volume 220x220x250mm and heated bed for ABS filament. I recommend building an enclosure if using ABS to reduce warping.
The Creality CR-10S can be found for under $400 and has a large build volume 300 x 300 x 400mm. This is what I would replace my Da Vinci 1.0a with in the future. Beast of a machine and it costs less than what I paid for my machine.

*PS you will have to assemble these printers yourself. I didn\'t have any issues with the Ender 3 I bought my little brother. Prints better than mine..

Peter, there are several discussions about 3D printing on the Tekscopes forum. Tektronix knobs have a lot more detail than radios used, but people are happy with the results. They have recommended the proper plastics, printers and software. Be advised, to anyone who wants to join, not just read. You will be kicked to the curb if you are an asshole. If you do get set up, you can post files so others can make the same part without starting from scratch. It can either be public, or private but if others add their files it would save a lot of time and headaches. You could even set it up at a show and demonstrate how it works.

Here is a link to read the group. You can find a link to join, if you are interested in Tektronix equipment.

https://groups.io/g/TekScopes/topics
This is a great group. No nonsense, professional, civil, stays on topic. As pointed out, assholes are not tolerated.
J
 
At this point, and given a very successful track-record with smaller pieces, I will focus on making larger resin-castings rather than a 3D printer with perhaps-marginal resolution. The nice thing about silicon molds is that they may be used over and over after a little bit of care in the making. I will let 3D printer technology evolve for a bit before investing at what I see is the level necessary to be useful for my intentions.

Thank you for all your input.
