I've been watching this video 3D printing guides: Calibration and why you might be doing it wrong and at the start (at 0:30) three of the first Reprap printers are mentioned (and shown):
- Prusa Mendel, and;
- what sounds to be "Cells".
Here is a screenshot:
which, to me, looks like a Mendel.
However, after having looked at:
... I can not see the "Cells" printer listed or mentioned.
Am I hearing it correctly?
Or is it "Sells", in reference to Edward Sells, one of the four authors of RepRap – the replicating rapid prototyper? However, this paper only mentions/shows the Darwin and Mendel printers.
