Transforming sphere robot

• Even with 3D printing in mind while designing, this print still tests your bed adhesion, overhangs, over/underextrusion, printing curved surfaces, debossed printing on curved surfaces, printing tall thin objects, printing small embossed features and more. Because its sphere design allows only a small portion of the parts to be in contact with the bed, weighs only a few grams, this makes a great printer tester.

 

• Everything is oriented correctly, supports are only needed under those big blasters of his and brim is advised but not necessary if you have your printer dialed in.  

• You can print it in any layer height you want but it has some fine details which are better shown in lower layer height. 

 

• For the inner core I would suggest to use PETG, ABS, ASA - something more flexible because of the snap joints. The outer shell can be printed out of any material but the PLA is the easiest to print.

 

• Number of parts is in the picture below and I prepared two beds so you can print everything at once. For the best results print those two beds in a different colour. 

Assembly: 

Assembly is not hard. Just connect R-04 (base) with R-08 (base connector) through the slots. It will stay in place but a drop of superglue never hurts.

Than position it according to the drawing. To the lower four snap in holes insert 4x R-03 (feet connector) and on those 4x R-02 (link). To the link just attach the feet. 

Connect the arms and head in a similar manner, but instead of R-03 (feet connector) use 3x R-09 (head and arms connector).

Tip: use fuzzy skin on the faces of armour and core, that are touching. This way it will have more resistance when positioning. 

And you are done! Enjoy!

 

Future plans: 

If you guys like this robot I will definitely add more. Like removable blasters, different type of blasters or heads and more. Feel free to write me your ideas and I will try to add them.

For example I started working on a Gatling gun attachment:

For cleaning of the prints you can use my mini utility knife. Is is perfect for these small parts.
