I find I often need Sharpies (small permanent markers) while working on bikes, and previously have kept my Sharpies in a pair of hooks, which was always pretty tenative, the markers would always fall off, so I've wanted to make a proper holder for a while, and I'm still getting familiar with Fusion 360, so this was a perfect application. While this works well for holding Sharpies, it could also be used for many other objects with about the same dimensions.
I was going to start with my pegboard 2 position blank - but realized that this was an opportunity to redo it from scratch and make it a fully parameterized model, especially since the original design didn't quite fit all the pegboards that I used, so I wanted to be able to fine-tune the dimensions.
I also sized the holes a bit large for the Sharpie body, as the silver Sharpie works best when it's stored inverted, so I sized all the holes for that. Of course, since it's parameterized, if you wanted to change the diameters, you could do that.
I've added the Fusion360 source files for the single blank and the 2 position blank to my pegboard 2 position blank thing in case that can be useful to anyone.
Sliced in PrusaControl which gives two shells. Support isn't needed for the main body but is needed for the upper pegs, but it's not too much support material. Should be a quick and easy print.
Other printed items in the photos
As you can see in the second photo, I've got a bunch of 3D printed parts on my pegboard. Here's a list of things in the second photo which I'm using with great results:
