This is a replacement wall hanger bracket for Black & Decker Dustbusters similar to V1320 and V1410 types. The 3D printed version emulates the stock design. The first photo is the 3D printed version, and the second photo is the stock version.

I used eSun PLA HF .16mm layers. 60 deg bed, 220 deg first layer, 215 deg subsequent layers. 15% grid infill. 3 vert walls, 3 bottom and 3 top layers. I used support under the cable restraint tabs, but it might work without support (it's tricky to add support).
