Kingroon, KLP1 - Foot risers

Feet risers for the Kingroon KLP1, to get better airflow for CPU cooling.

They are a swap in replacement for the existing feet, and raise the printer by 10mm (originals are 10mm high, theses are 20mm).

I Just glued some soft foam packaging on the the base contact surface, which I just used scissors to cut to shape (I just used a very thin layer of PVA to glue the foam to the printed feet).

I turned the printer onto its left side to access the base, unscrewed the originals, reused the same screws, and screwed in these.

I printed in Black PET-G, but I don't think material choice should be a big issue.
