I usually use the smooth side though.Below it we have a flow calibration cube in the same filament.Next we have a couple of practical prints. They're a custom design wheel for a robotic lawn mower I made. Printed in black ABS filament with a large...

This is neither convenient nor practical. So I opted to use a stand that allows the filament to pass through a hole in the shelf where the filament is mounted. Also, the first version of the stand was converted to use T-shafts with...

I used GIMP instead of Paint.net for drawing the topography; Octave instead of MATLAB for plotting the 3D model; MeshLab for simplifying the meshes, instead of Microsoft 3D Builder; Freecad2 instead of SolidWorks for the tunnel and the World Engine;...

I haven't test this yet, so I don't know if the flower part is printable; I generated the gcode (with support) and it seems so. I could not find any artwork of the book, a fan art nor even a drawing of them, so this is comes out entirely from my...
