fix/build last version of plotter, clamp, camholder

[pinar-oray]

I made this a separate issue than preparing the demo so we have the small visual fixes on the other issue when the time comes.

• Last version of plotter: link to onshape studio
• Latest version of clamp: link to onshape studio
• Latest version of camholder, most likely will tweak with the camera placement on this: link to onshape studio
• Full assembly file of these versions: link to onshape assembly

To-do:

• [x] fix camera placement if necessary
• [x] build and assemble the latest clamp, camholder and plotter Tuesday morning.

• Clamp does not work yet (easy fix: rubber)
• Cam holder to be glued (we need to rotate the picture in the code)

Clamp design change:

remove top part nut, just one hole => should this be fixed or a bit bigger than the screw? maybe a spacer between screw and 3D-printed part for not putting direct pressure on the clamp part add rubber to bottom part will print tonight

So @pinar-oray and I took over the clamp task.

We fixed the issue that we were not able to fix it in place using the hand screw. I also took care of gluing the magnets along with the rubber (which turned out to be harder than expected 😅).

We finished it today and here is the result: https://i.imgur.com/Gxj21lz.gif (can't embed in GitHub for some reason). The clamp part is now completed.

And here is a status update on the current build:

After my first week working on the clamp, I noticed a few flaws in the current design and I was also wondering why it was so hard (took so long) to come up with it, so I tried to do a little prototype of my own.

So in about 3 hours of work I designed and printed the following working prototype (just missing the replaceable magnetic parts, not a big deal):

It features way less (moving) parts and a simple M6 screw is used to tighten it. We can clamp the remotes and tighten this in the same direction that we want to apply the pressure.

We could have fitted this kind of clamp just under the main plate and leave the tightening "gear" appear on the side.

I am not sure that we'll have time to use that version instead of the current one though.

Latest update: we have done minor changes to the clamp during installation, so me and @nourguermazi updated the CAD designs to reflect them. Mainly there are no more walls to hold the magnets, we just glue them in. Also the holes connecting clamp tops to parts underneath the board are wide enough so that a 4 mm screw can easily go in without it being too big for the holes. I drilled the holes with a 4 mm screw on the build to achieve this but now printing the latest version should yield similar results.

• This is the assembly of everything
• This is the plotter
• This is the clamp
