Thanks NewMatter, great to hear you have done some tests with other materials, I have already been thinking up ways of getting the print bed to work, just wanted to know if the extruder was up to it really.

I was expecting that to be the case with the spool, and my next question was going to be about the ease of use for feeding filament if it was located under the unit.
So has there been any discussion on the aesthetics/convenience of just having a spool sitting around behind the unit and the possibility of a MOD-t spool holder? My first thoughts would be a simple bracket off the back of the case but this would of course detract from the clean minimal design. So my next vision would be a separate box to hold the spools along the same look of the printer. My main concern is that if this is designed to be the low cost 3D printer for everyone, then for the everyday family to have one of these sitting on the table, desk, or kitchen bench, the management of the filament needs to be contained in a way that is tidy and convenient, and also protects the filament from moisture, dust etc.
