Prusa Spool Display Shelf

Model should print easily without any modifications. when inserting your recycled spool disc, you should insert the edge of the disk towards the wall mount side with the disc just underneath the tab, then slide the middle hole over the center of the base. It will be a tight fit and will take a little effort, but it will snap in place. you can screw right into the base with some screws or use any other mounting hardware of your choice. models displayed in the pictures on my shelves were found here on Pintables.
