This is a replacement adapter for a push broom. If your adapter breaks, like mine did, this might be a direct replacement. I modeled it from scratch based on measurements taken from the broken part. Note: it will probably NOT be strong enough using PLA, especially in cold temperatures or with rough use. Stronger materials are needed, and it should NOT be printed upright (weakest direction for how it is loaded).

Regardless of material, I recommend 100% infill.
