SecKit SK-Tank v2 Dome

This is a version of my dome design for the SecKit SK-Tank, for version 2, with 2020 aluminum extrusion for the legs.

Most, if not all, dome accessories for the v1 should also work on the v2.

I found the dome platform to be particularly difficult to print well enough to get the legs to fit.  I plan to refine the design over time to be easier to print and easier to fit the legs. For now I have these recommendations for how to print it:

• Use a short layer height  (I used 0.1mm); this should remove the need for supports;
• Print at a low speed (60mm/s or less);
• Use no supports;
• Print the platform upside-down, with the leg sockets pointing up;
• Use a brim.

I printed in PETG and I find the platform to be not quite rigid enough, so I plan to address that sometime too.

The spacing of the top frame holes is different than in v1. This version is suitable for mounting with the dome legs in the Y direction. The leg sockets are for 2020 aluminum extrusion. For mounting the legs in Y as described, they should be cut to 210-230mm.

The dome feet are similar to the originals, except also for 2020 extrusion.

The spool stand towers now have a slight inward tilt so as to grab the spool axle better.

Most, if not all, dome accessories for the v1 should also work on the v2.
