This is my tool tray, designed to hold all the little tools that I got with it when I ordered through Bilby CNC. This set holds: Vernier Calipers Feeler Gauges Nozzle Spanner (7mm wrench) Hex Keys - 1.5, 2, 2.5, 5mm Scraper Small side cutters (mine are ~15.8x 7.8mm head) Small brush Small flathead screwdriver - widest around 8mm Tweezers 2x SD cards 12g tube of super lube This is a derivative of basically any tool holder here, except for that mine was developed with the kit that I received :)
