Dual Vacuum gauge holder

This is a dual vacuum gauge holder that I use to synchronize the carbs on my motorcycle. The gauges are Bosch FIX7803 and cost around $25 each. I got tired of trying to read them at various angles, so I made this Thing!! I also included a file for a hold down clamp, which is not really needed unless you use a smaller gauge. If printed as is and your printer is accurate, you will NOT need the hold down.
