HULA Feet Adapter for Sovol Zero

This is an adapter for the Sovol Zero that allows the use of the HULA foot design by "thrutheframe" (available here: Makerworld HULA Foot).  I recently picked up a set of these through Voxel, but they were designed for the Bambu Labs machine.  So, since the foot on the Sovol is different, I designed this to serve as a replacement for the inner foot of the HULA foot.

This is a 2 part build.  The TPU portion replaces the stock feet on the printer; and the PETG portion replaces the mount (inner foot?) in the HULA foot and serves as a press-fit socket for the TPU foot.  The TPU foot has a square edge for indexing on 3 of the 4 Sovol mounting locations.

…And since nothing is ever easy, the 4th does not have one.  So that TPU foot has to be smooth.

In total the HULA foot with these installed adds about ¾" (20mm) to the height of the printer.

I printed mine in Polymaker Panachroma muted matte blue to match the Sovol Color (well, nearly match), but these would probably be mechanically better in a PETG or a silk finish.  I'll probably re-print them in a black PETG, with the temps a little high for the gloss finish.
