Description

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 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 McMaster-Carr - https://www.mcmaster.com/93038A126/ 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 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. 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.
