I made this bumper to protect the corners on some shop furniture I've been building, and to give the pieces a more ‘finished’ look. 

The bumper is about 3.75" tall, 1.5" wide, and 1.5" deep. I've used some ¾" #6 pan-head screws to attach them to my furniture. 

These printed great in some cheap Elegoo PLA, costing around $0.33 a piece in filament.
