My first original file! Not a new idea, but 100% mine.

Printing with higher infill will ensure the model is heavy enough to hold the door open.

specifically designed with small hooks on the bottom so it will not just slide across carpet.

added 4 gcode files. all are 25% infill and are different lengths (inches).
