A couple of days ago I started a GoFundMe campaign to acquire an Ultimaker 3 Extended 3D printer. This printer will allow me to make much more intricate and accurate 3D prints, of skeletal structures, biological organs, functioning models of machinery, etc. The reason is that this printer has two extruder heads, which means that support structures can be printed simultaneously with the actual model, but in a second material that is water soluble. Support structures are necessary because gravity causes drooping, which destroys otherwise great models. The campaign can be found here: https://www.gofundme.com/3d-printing-for-blind-students
