Are different sized nozzles available for the 3Doodler Start?

There are no different nozzles available for the 3Doodler Start at this time. However, the 3Doodler Start filament is malleable for 10-15 seconds after extrusion, so you can experiment with different textures through manipulating the filament while it is still soft.

How do I use the DoodleBlocks™?

Simply draw into the grooves of the DoodleBlock™ to form a shape, wait 10-15 seconds for the plastic to harden and then bend the DoodleBlock™ to release your Doodled shape. You can then fill in the shape if you want, making it more solid. Once you’ve traced all the pieces, you can then use your 3Doodler Start to join them together to form your finished 3D creation.
