Want some kickass knobs for your engine bay? here you go. Designed to fit perfectly in the recesses of the stock access panel. This general process is what I use to add white-on-black Logos and text to any of my prints (Shift knob, coilover dust cover, etc) What you need: 4 printed knobs M6x1-12 flanged hex head bolt (https://www.mcmaster.com/90166A144/) White filler epoxy (I prefer Mohawk's white Epoxy Putty stick) Epoxy adhesive (I prefer West System G/flex 655) Sandpaper: 220, 400, 800, and 1500 (Add 3000 and up if you want a more gloss finish) * Print the knobs and remove any support * Sand with 220 grit until there are no filament gaps visible * Mix and fill in your white filler epoxy, pressing into the gap left for the H logo. * Sand again with 220 grit until the logo becomes visible and you remove all excess filler * Increase in grit to 400, 800, and 1500 (or beyond) until the finish is to your taste * Apply a bit of mixed adhesive to all 'interior' surfaces on the knob * press in the bolt, making sure to squeeze out any air bubble. The metal flange should sit sub-flush to the outer plastic ring of the boss * Smooth out any excess adhesive *Allow to cure *Enjoy
