Key Hole Dowel Bracket

I created these simple brackets to hold my shop towels while utilizing the space on the sides of my metal shelving. 

The inner and outer portions of the keyhole lock size/diameter can be adjusted in Bambu studio under the objects tab. Out of the multiple shelving systems with keyhole system they all vary in size so hopefully allowing this to be adjusted makes this print universal for anyone. it also has a little locking screw to make sure the dowel does not fall out.

Wooden dowel used was 22mm/ .86"/ 7/8"(not cut to fit lengthwise in photo)

Pictured brackets were printed in PLA Basic since there is not much weight and used within a fair climate. Please take filament type into consideration for your application.
