This is a remix of DownRight's KitchenAid Stand Mixer attachment hanger. One of the models you can print as a single piece.
The other models allow you to orient the pegs at 45 degrees and print the pegs in one piece.
Also you can install the peg as a single piece with a #4 flat head wood screw.
All screw holes were designed for #4 wood screws.
The author remixed this model.
Edit 5/27:
Modifies the single piece unit so that the angle of the pegs is now 55 degrees to allow the paddles to sit angled and thus larger accessories. Thanks to everyone who suggested the improvement.
Original:
Allows for the pegs to lock in place and not rotate when screwing in the baseplate and not attaching with double stick tape. Also the pegs are now printable as one single part not 2.
Additional 3 hanger model is a single piece print in scenarios where you don't need to reorient the pegs.
The single hanger can also be used by itself and installed with a #4 wood screw.
