			Created new gitlab project repos.

			I've considered many possible ideas for kinematic style mounts that could be automated, but I don't think any have been viable yet. I need to look at more mechanical examples, hand draw some ideas and just try some experimental CAD. The round head bolts seem passable, but finding other generic bolts the right size may not always be easy. The shape of the plastic parts has to be complex to accommodate multiple features. A latching mechanism needs to work by moving along multiple axes and attachment of levers is not easy either.

			Meeting. I reviewed emails and doc changes. It sounds like a lot of good progress on projects, but not a lot of uploaded files yet.

			Also thinking about tool changing. Hoping there is some X,Y,Z dance the machine could do with a tool to release and latch it into a mount without extra motors/servos etc. A tool mount that could do that maybe complex would it might beat having extra motors easy if it is elegant and has great MTBF. No living hinges or flimsy push-push latches. Maybe it needs metal springs. I wonder if the mount mechanisms could actuate with 2-3 axes of motion if needed.

			Reading more about kinematic coupling and I looked up William's extruder work from today as well. I wonder how accurate 3d printed plastic couplings could be if bolted together. That appears to work for camera mounts, but I question the repeat accuracy. I also wonder about embedding 3 nut catchers in the carriage in such a way they would be compressed and not move much post assembly. Adding the requirement of complex off the shelf metal parts like balls and grooves would likely add cost. In the long run, they could be milled, but the accuracy requirements are likely higher than what will be achieved soon.

			I responded to an email from Chris about the simple extruder. More thought and reading is needed on the quick coupling concepts...

			Doing a little more research on kinematic coupling and tool changers.
			Immediately the need is just for a quick couple, but it would be nice if it was at least partially scalable for future tool changing needs.

			I think there are ways to make a dock that effectively catches and releases tools without extra servo or stepper motors by using the force of moving the head in/out of the dock. I also think 3D printed plastic parts might be accurate enough for most printers if the design is good enough. I'm not familiar enough with the mechanics of kinematic coupling yet.
