No fair posting the answer yet if you saw it where I did.

I’m taking a shot in the dark here and using what’s in the background as a hint. Is it something used by a luthier?

Nope, but the person who made it plays banjo (and mandolin, and dobro).

Amish made bandana stretcher with lint roller?
That would make a nice Amish bandana.

making original bank wrapped rolls with key dates/mms showing on the ends?
And a piece of doweling in the middle. I don't even thing the usual scammers are that brazen. (And, no, that was not the correct answer.)

A hilarious refrigerator alarm
Possibly a prototype of the Al Bundy toilet paper holder
Yeah, um, no. I'll post another picture that should be a decent hint in a while.

Here's a hint.

some type of printing device?
Is it an elaborate phone stand?
Yes, but built for a very specific purpose.

Does it buff planchets?
Nope. IPhone users might be able to recognize what the phone is being used for.

Coin stand to shoot the edge?
Yes. So why the apparently complicated nature of the device?

Reduce vibration and to control light?
I suck at this. Even in plain sight it took more than one guess.
The coin rotates as the phone slides? Why the band?
On second thought, the phone looks like it would be stationary.
Close. Look at both pictures

Does the grey band have something to do with white balance?
It's a cell phone holder..... easy! Next, show the combination Moravian banana peeler and cement mixer.
Panoramic pic/view of edge. What is the device for?
The top section slides and the band turns the dowel? The phone films the edge.
If you look at the first picture, you might be able to see a string wrapped around the base of the large post in a groove. The string is attached to what looks like a piece of heavy foam. As the "sled" (frame with posts and Amish bandana) is moved along the track, the string around the post rotates the post in front of a camera taking a panoramic picture. The Amish bandana is used to trick the camera into thinking there is a background that is being panned, which gives better tracking when shooting a panoramic picture of the edge of the coin. Here are some results.
Ron Landis built this last night because he wanted something better than a small turntable he was using.

Clever. Before slabs, I always felt the edge to see if if the reeding was sharp on an uncirculated coin. Seeing the edge in panorama is very cool.
WOW - musta been smokin something good to devise this. Haven't quite figured out the whole bit yet tho.
Congrat's on originality! Is that a wool scarf involved?
Its a catapult to shoot the iPhone over a moat
Well... I could have guessed for three days and not come up with the right answer....Of course, I do not have an iphone (Android guy) and I do not do coin photography...so at a disadvantage right away...
Cheers, RickO
That's cool!

I'm thinking is a cut off t-shirt sleeve.

This type of product is also referred to as a "roll-out" photo. A turntable with an urn or other artifact placed in the center rotates in coordination with a panorama camera to produce a flat, accurate image of the side or edge. (One of the best uses I've seen for a cell phone camera.)
This is actually really cool, thank you for sharing
all around collector of many fine things
So Ron's going to make some modifications to his device, adding a crank to make the motion easier, and some stops so that it doesn't go past 360°. It's what happens when a tinkerer gets in his groove.
I doubt that he's familiar with the term "roll-out photography," but I'll mention the term to him. A quick search only turned up the technique for DSLR setups, mimicing the slit-aperture panoramic photography done with film cameras like the Widelux.

Back before time began, slit-aperture cameras were combined with a gear train to rotate the turntable at the correct speed for the circumference of the subject.
Suggest to Ron that he go to 370-degrees. This will allow for cropping the ends of the image for a smooth appearance and also avoid inadvertent clipping. The goal is 1+ coin rotation per 1- image width.
