Having discussed this a bit, I've just designed a rather large part that's printing now in carbon fiber—infused PLA (at a whopping 116.6mm x 117.3mm x 142.0mm with a raft). So this will be my first tall part that's diagonally-aligned to get some base footprint as well. Not sure if this will work as I intend it to but I wasn't in the mood for having multiple parts which fit/join together. The Robo C2 sits atop a tall Ikea corner shelf. A pair of these will fit under the back two legs of the Robot C2, extending behind the shelf in such a way that a roll of filament can be loaded sideways in the shelf space below that. At the moment, I have a fat dowel that will act as the axle but I might print one so that it's less likely to slide sideways. Oh, and I'm really loving the MJPG-Streamer server now with the webcam. I can monitor the job remotely without being in the other room.
