Hinged Dust Cover for 16mm CB/Aviation Connector

thingiverse

I designed some hinged "dust covers" for a project I'm working on. I prefer using what are commonly called CB or Aviation plug connectors for stepper motor connectors because they're inexpensive, easy to connect, and can carry a decent amount of current. Most importantly, the opening is keyed so the connector won't spin when inserting and removing the plug. You can find the connectors on Amazon at https://www.amazon.com/uxcell-10Pairs-Thread-Aviation-Connector/dp/B016FCZ5SS This cover fits the common 16mm thread connectors (e.g. 3-pin, 4-pin, 5-pin and 6-pin). I haven't tried larger pin count connectors, but if it's 16mm, I'm pretty sure it'll work. Snap the two parts together with some care, and they'll stay in place. I added some mild camming on the lid so it'll stay at 90 degrees even if you install the unit so the lid closes down with gravity. Designed to print with no supports at any resolution that works for your printer. Remember to flip the lid over 180 degrees (I saved as STL directly from the assembly in Fusion 360 and it kept orientation).
