I’m taking a stub at modifying @pacificmeister 's mast back clam so it is more maintainable. I want to be able to disassemble the build. Specifically the tube from the mast back clamp, which means no glue is involved, neither between the back clamp and the tube, nor for holding the wires in place.
The design (frozen, I’ll update the thread upon changes):
I still didn’t connect it to the part that is connected to the clam, and I still didn’t add the screws that will hold it in place (I’m going to plant a square nut to accept the screw).
Some pictures (printed at this stage without the outer cover for the tube):
I followed the same idea for water-tighting the tube/print as the one used for the seal mount (two o-rings). I did modified it a bit to avoid >45 degree overhangs (and support).
For the cables, I’m using rubber grommets. I might glue these in place (as there is no need to remove those from the print).
It is not water tight yet - https://photos.app.goo.gl/htr2ThprYOWHX7Xl1
It seems like I have two separate breaches
From one of the grommets - This might be a result of my design avoiding support (also in the holes for the grommets. Glueing can work here…
From the actual print. Specifically from an inside corner. This can be the result of my slicing parameters (10% infill 0.2 hight, thin shell, make the first iterations faster). This might also be the result of my solid being an assembly of several parts (for design simplicity) - there might be a gap there as a result of rounding errors. I’ll also try and add fillet to that corner. One experiment I’m going to do soon is to print a similar part with no wire holes, so I nail down the printing parameters for water-tight print (or epoxy it if I have to…)
