3d printing steps
Print the parts with a 3D printer. If you want to make a left hand version of PushPull you need to mirror all parts.
We used facilities of the 3D Labor of TU Berlin. Before painting the material it is necessary to put all 3D Printed parts into hot water for about 2 hours. It is also possible to use online 3D printing services like, Shapeways. We suppose that watering the material afterwards is not necessary in this case. Also you can directly have it printed in a certain colour. This way painting these parts will be unnecessary.
Alternative printing methods may be used, ask your local maker space.
