T4 Seat Add On

This is the remix of the Master Seat Add On https://www.thingiverse.com/thing:5529643 to fit the T4 seat contour.

Note that have a split version that allows easier printing with minimal support. Also it allows split printing of the bottom in PLA for firm support and TPU top for the cushion. If you prefer to print it all in TPU, you can do that with the non-split version.

I use 5% infill gyroid for top for hard TPU. 10-15% if you have softer TPU or TPE.
