[QUOTE="mikkomakk, post: 3649546, member: 105826"]Hello fellow numismatics! Lately I decided to move my completed collection of [URL='https://en.numista.com/catalogue/pieces1445.html']Norwegian 5 krones[/URL] (I'm collecting all Norwegian coins pre-1875) from a display I had, to proper storing units. I wanted these storing units to offer easy access to the coins, and also protect them against light. As you can see on the pictures below, they are all stored in capsules which should be pretty air-tite. You probably wouldn't think that this average collection is worth capsules, but I plan on having these coins for many many years, and the capsules costs a few cents. They are also in mint condition, which in my opinion warrants proper handling and the best available holder, which in this case is a capsule. Plus the box I have just made! [U]So what I did to make this:[/U] First off I found my collection and started doing some measurements. When it comes to 3d-printing, it's very precise. You usually print at 0.1mm to 0.2mm. The lower the finer the print. Lower mm also results in extremely long print times, so it's usually only worth it if you are printing a bust (not tittays) or highly detailed models.

I also 3d printed these frames, and was planning to have glass over them (like I did on the white frame), but without a proper UV resistant glass (which costs a fortune) I don't think it's a good idea to keep them on display.
