These are feet for top mounting spool holder on an AnyCubic Kossel Delta (20x20 Alu).

I've printed with PETG, any type of filament could be fine.

They can be clamped using the M4 screws included into the AnyCubic bundle (I've 4 more left-over screws).

Consider to change the filament drive motor's position, upside down and on the middle top part of one of the axis's frame. Just look at the photos and you'll understand.

• (ITA) Attenzione, suggerisco di cambiare l'orientamento del motore sottosopra, posizionandolo a metà della colonna/montante, come da foto.-

Any questions are welcome, best printing to everyone.

Honeycomb infill, maybe you'll need to smooth the screws' holes.
