Nice spring! I haven't tried one yet but springs seem like they present a real challenge. How many scans did it take to get the entire thing?

Hi
think I did 16 scans, 8 from side 8 looking more from top and side then combined both sets I did not have much problem but did use turntable, don't think I needed all 16 scans in the end but looks ok to me. going to try printing it just for fun ;-)

this is one of the spray I use now, its very good, they also do contrast spray that's more permanent but easy to remove later

For people in the USA there is also this option for spray:

A bit less than twelve dollars US per can. I've used it for other purposes. It wipes/washes off very easily, and is a great matte white finish, perfect for scanning. Various colors, but why use anything other than white?

That's what I've been using. It's $10 a can at the art supply stores around here, works great and is very easy to wash off. I tried the industrial marking chalk that McMaster sells for $5 a can, but that can is meant to be sprayed upside down and comes out like a fire hose.

got the top bit lined up now :-)

I'll put up a pic or scan of the contrast spray tomorrow, it stays on when handling but washes off with brake cleaner I use in the workshop ok.
the developer is better than others I have tried, goes on much better and only needs a light spray, others spit out bits that show in scans sometimes,
I'll have to look see if the chalk spray is in the arts and crafts place in UK

The main reason I like the chalk is that is is so easy to remove. Just rinse with water. I've had bad situations with coatings that needed solvents for removal where it didn't completely come off and I wasn't going to expose the part or myself to the amount of solvent (even if it was denatured alcohol) need to get the hard to remove bits. With the chalk a quick rinse under the tap and a dip in the ultrasonic with water and dish soap and the part comes out like it was never sprayed.

yea you have to be careful with the contrast spray but the developer is just like the chalk spray its just a powder that rubs off with a cloth or washes off as you say,
it does come off if you handle the part alot tho and that shows in the scans.

I always do a test first to see how easy it comes off and to see if the part is affected by it.
or like the camera and this Can I did not use any spray, just have to be careful with settings and you can still get good results even on black like the camera

I've had a bit of trouble scanning things (un coated) that have high contrast like the black lens and the white label. I tend to get a lot of holes. How/where do you set your exposure settings to get good results with things like this camera?

how I did the camera was, set up the camera and projector to get a good red sign wave on the object i.e. projector full brightness and camera aperture open to get as much light back from the black surface as you can ( you will need black background ) then this will be to bright to calibrate so turn down the projector slide bar in David don't touch the camera or projector!
calibrate then turn up the brightness again to scan the object, placing the object at the correct angle also makes a difference, I played about moving the object and seeing when I had bigger sign waves, as long as you get something to line up the next scan with it should turn out ok and use close holes on fusion,

I did not want to spray the camera but for one hard to get bit I did dust a very small amount of powder on it, it does not take much to make a difference.

main thing is don't set the brightness for the calibration corner set it for the object and adjust brightness in the software to calibrate, if the label was to bright I do a scan with it turned down again then edit the scans in shape fusion

hope this helps
