It's been a while since I posted an update... So here's one!
I'm a bit slow when it comes to building (or assembling) but some progress has been made. Mainly I've been 3D printing various bits. This is a bit time consuming as I have to design the bit, print it, test fit it, modify the design, print it again, test it again, etc, etc. Printing with a $500 DIY Chinese printer is not the fastest. ;-)
Anyway, here's some pics on what's been done.
