I wanted to raise up the spool holder a few inches to accommodate the larger 12" spools and still use the top plate of my enclosure. Instead designing the wheel and to save plastic I made these little feet to raise up the spool holder by 2". More than enough. I put room for drop in nuts and bolts and pass thrus for zip ties so it attaches easily. Just print 4 of them.
