So after not being satisfied with the options for fog dash pulls I went down the rabbit hole of making custom knobs for a few of my planned upgrades.
Sharing what I've done here:
Files:
Overview:These are modeled after the early style knobs. Some knobs are at half-height as I am planning on putting them under the dash and wanted them to be lower profile.Process for those who want to make custom knows:Download the blank STEP file and cut in your own icon,You can find good icons...

Overview:
These are modeled after the early style knobs. Some knobs are at half-height as I am planning on putting them under the dash and wanted them to be lower profile.
Process for most:
Just download the .STL file and upload to an on-demand print service like
3D Printing Service | Shapeways - https://www.shapeways.com/ I haven't done this, but I would wager that Black Smooth PA12 or any Smooth Material would work.
Or do what I did find a neighbor that has an SLA 3D Printer. Often referred to as a "Resin Printer" and have them printed that way. This is probably the cheapest way as most people with 3D printers love excuses to use them and show them off. Often only needing to pay for material costs. You can print them on a "normal" 3d printer, but the resolution will be poor and you will need a lot of sanding to make them work. Not recommended.
Process for those who know CAD:
Download the blank STEP file and cut in your own icon,
You can find good icons to use via
Noun Project: Free Icons & Stock Photos for Everything - https://thenounproject.com/.
Either import directly or use it as a guide for your own line art.
I normally try and make the line width 0.75mm wide and 0.50mm deep.
Notes:
Tap the base hole as M5 and the set screw hole as M4.
I use this for the set screw

Post Process and Paint Fill Process:
After Tapping the Knobs. I use a spare M5 Screw in a drill to chuck the knob.
I then use
Novus 7136 Plastic Polish Kit starting at 3 up to 1 to get the surface a bit shinier.
For the colored paint Fill, I use Enamel paint meant for miniature model painting. I like Humbrol but Testors work great as well.
For White is use a
Presto! Multipurpose Correction Pen The tip fits perfectly into the recesses and makes filling white super easy.
If possible use an
Ink Syringe with the enamel to fill otherwise I just use a paintbrush or needle to get it filled.
I try and dab most of the paint off. This leaves it pretty messy but it's just a thin layer to remove next.
After the paint semi sets up. I take some Goof Off paint remover and wipe the surface clean with a microfiber towel.
I repeat the paint application/wipe removal as needed till I'm happy with the fill.
