replacement feet for this trash bag holder: https://www.amazon.com/dp/B001VGW24E/ref=cm_sw_em_r_mt_dp_U_e1-.Cb9J2VW2Z
Love this bag frame, but the feet eventually crack and break, so I drew up some replacements
You will need four total, but two of them need to be mirrored. You'll end up with two "left" and two "right" feet.
Supports will be needed. I oriented the part with one set of through holes vertical, which meant that the other set of holes is horizontal.
Print with something tough like ABS, Nylon (Alloy 910 is what I used), or PC. Needs to be able to withstand a fair amount of force and abuse.
