I have the Suncast slat wall system in my garage and I am always am looking for a pencil. https://www.suncast.com/sw04.html So, I decided to design a pencil cup that snaps into the slat system to hold pens and pencils. I printed it in optic yellow so I could always find a writing utensil. It is designed for the Suncast slat wall sections which are sold by Home Depot and other home improvement centers. https://www.suncast.com/sw04.html https://www.suncast.com/sheds-storage/garage-storage/slat-wall-systems.htmlSettings (Suggested) Raft: On Supports: On Infill: 35% Suggested to make sure 'pegs' are strong. Shells: 3 Layer Height: 0.20mm After printing,clean up and remove raft and supports with an xacto knife. Be careful not to damage pegs during cleaning. File as necessary for good fit in slat board.
