This is a space-saving mod to minimize the footprint of the CR-10. It also requires a 20/20 top-mounted spool holder.
Print 2 of each leg.
Use the stock screws that come with the unit.
No extra hardware is required.
NOTE: These were printed horizontally using supports on the non-decorated side for best design detail.
Credit to the Original artist:
I purchased the .stl that I used to create the legs and the licensing states that they cannot be shared or sold in their original format. They have been changed considerably for this mod so sharing them here does not violate the licensing. I also contacted the artist and they said that they were happy to be of any help.
