MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
One problem is that the filament is not straight as it comes from the spindle. Sharpening is also a lot of work (I have noticed this at the other greenhouse-dom with woodsticks, so I created a printable version). The sticks can be printed directly onto the print bed. This goes very quickly.
But you can use wood or other rods, if you find something suitable.
