ER11-ER32 wipers for collet holders.
Should print best in the original orientation cone down.
I printed them on a i3 MK3 with structured bed, 0,4mm Nozzle, PETG, 3 perimeters and 25%infill.
For ER11 up to ER20 i suggest using a brim (i used 3mm) and tree supports for lateral stability. The others should be ok without brim and supports if you get proper bed adhesion.
The felt i used was 3mm selfadhesive felt meant for felt pads for furniture. You should be able to find this in any hardware store.
