Entry 20 : Building The Crank - CNC Decoration Parts

This entry will be discussing about creating decoration outer layer for the version 2 MO-3 crank box.

Lin Yew and Ronald Chua suggested to use the CNC to carve out the decoration parts from a 1cm plywood.


It took atleast a day to completely carve out all the decoration parts. A slight issue with carving plywood is that the material peels or cracks when carved with the CNC machine. Therefore, accidentally creates some somewhat awful looking surface on the decoration parts. So, I painted those flaws with black spray can and it somewhat works.

Entry 21 : Building The Crank - 3D printing

This entry will be discussing about the continuity development for decorating the MO-3 crank. I've 3D modelled 3 items for printings: - 2 Handles (UpDown and LeftRight) - KEV-7 Leap Motion holder I took atleast 2 days prototyping the size of the 3D printed prototypes to see if it fits in the crank's handle. It took few prototype to find the correct scale. After settled with the correct scale, I've loaded up the Tronxy X1 3D printer with the handles. The first print was a success while not so for the other print. It was too big and technical error that causes the model to be displaced in layers. Thus, I loaded the same model and printed it again. It failed due to knotted 3D filaments. Third try was a success. Total it took 2 full nights to fully print 2 handles. After that I've loaded KEV-7 Leap Motion holder into a bigger 3D printer (beside FabLab's main Mac) and start printing the model. Due to too much pink 3D filaments, Ron and I decided to use the p...
