Float arm construction in 3D printing

[CaolIla]

Hi, one of my best conception 

 

 

I build 2 big arm to compensate the weight of my aluminium housing, the 2 lights bigblue and the 2 flash... at the pictures you see my old S2000 but now  since 1 an 1/2 year I have 2 retra pro

Hope this will give you some idea.

 

 

I made some new floating arm, but I 'don't have any picture.

The new one have the same shape but ... I build a tube to put the fiberoptic cable from the bottom to the top.... no more  risk 

Next step ist to make the same with the arms where I attached the flashs.

Great idea!

I made 3d print design of a modular set of float blocks that fit over ULCS arms.

 

They work but are not better than high density foam blocks which I already have. They are more buoyant, but they also weigh more than foam out of water. It was really more of an experiment in making a water tight print, but not good enough that I use them.

My idea was to have only the arms nothing else...  a minimum of components 

I'm happy with my solution . but now that I can print in PETG I will try make gain on the side of the weight.

 

The idea is to make a thin external structur and recover with carbon fiber and epoxy.
