• 1/2″ Snap Rings
• 9/16″ Snap Rings – Useful for going on hex shaft without first turning it down to 1/2″
• Tubing Connector for 7/8″ tube – 7/8″ aluminum tube is a similar OD to 1/2″ PVC so we can use it for stronger Protopipe mechanisms.
• 5/16″ O-Ring – These can go over 1/2″ thunderhex shaft and work similar to VEX IQ rubber shaft collars. This is useful for quick prototypes or places where you might need to adjust often or you just don’t have shaft collars. 
• 1/2″ OD – 1/4″ ID Aluminum Hex Tube – This is 6061 hex shaft that for us at least came in slightly undersized so it fits in bearings and hubs easily. It also comes with a 1/4″ hex hole so you can you it as a spacer for 1/4″ bolts or an adapter down to 1/4″ hex if you need to make a small mechanism. The 3/4″ to 1/2″ is also useful if you need a bigger hex profile.
• High Flow Solenoids 1.0 CV – These are the high flow solenoids that we used on our 2018 cube launcher mechanism
