This is a 3D printed magnetic extension holder for 3/8 inch socket extensions. Has powerful magnets allowing it to stick to vertical metal surfaces. I printed this in PETG plastic for more heat resistance then the typical PLA plastics used in most other 3D printed items you’ll find. This is currently a side job for me. I work as an Automotive Tech and originally made this for myself, so I know it does the job. If you are to use this for an extension much long then 16 inches I’d recommend getting 2 of these for more secure holding power
