Update: Printed latest version with PETG, skirt adhesion only, 90% infill, .2mm layer height ("regular" fineness on my Cura settings). The PETG will likely hold up better than the PLA, which deforms when held in stress over time. PETG is a little tougher (if flexible) and may be better in this role. Much happier with the typing angle. Will re-edit if these feet deform over time. --- Originally printed with PLA, used a raft, buildplate support, 50% fill, printed fine with a .4mm nozzle. Handy to gang two of them, so you can replace both feet at once. Works just about like the original - no noted differences.
