R4-D4 dome lid modification - part 5

 Right, on with the next re-re-design.

This first test print was in two parts, but could be combined into one. I did it as two for best print orientation purposes. Managed to get a good print and the piece fitted together perfectly!

The hinge part got strengthened up to stop any flex. The pivot pin holes were also reduced in diameter. All adding to less play between the components. Meaning, hopefully, less issues with alignment of the lid when closing.

Testing clearance of servo arm in closed lid position.

This will all be controlled with the Life-form scanners activation. But to add some flexibility in the lid servo movement, I’ve test fitted some springs.

Next up was to glue the panel onto the lid panel & the magnets onto the underside of the main lid.

Mixed up some more Araldite to attach the 3D printed part to the wood lid. This was clamped in place. One of the clamps slipped a bit so the 3D part moved out of alignment for where I wanted it :(

Once dried I mixed up a small amount for the first magnet. I placed a piece of masking tape between the magnet and washer so the Araldite wouldn’t bond to parts not required to be bonded.

I then clamped in place.

I bonded one magnet at a time to help with alignment of the panel. Once first magnet had dried, I went on to bond the second magnet in place.

.....next is to paint the parts again.
