None of the plastic bag holders I downloaded and printed met my needs due to design or being too fragile, so I modeled one suitable for my needs.
Criteria: -
I recommend 3/4 walls +4/5 bottom/top layers for a strong base. Infill choice not really important unless you only use 3 walls, in which case gyroid 30%+
Last, its designed to use a truss-style screw when mounting to avoid snagging the bags and rags
The author marked this model as their own original creation.
