Filament Spool Shelf Rack Stand

myminifactory

After not being able to find a spool storage system with the features I wanted, I decided to design one myself. This standalone spool rack has 5 tiers and can hold between 45-50 filament spools (depending on sizes and brands). Material costs are approximately $40, depending on wood quality. UPDATE: I added a holder for spool bags that hangs off the shelf's side. Materials: • 2 Wood Boards, 1" x 12" x 48" • 5 Dowel Rods, 1" x 48" • 40 #8 3/4" Wood Screws • 20 #10 1-1/4" Wood Screws 3D Printed Parts: • 20 Dowel Mounts • 4 Shelf Feet Tools: • Hand Saw • Power Drill • Sandpaper (120 - 220 grit) • Measuring Tape/Pencil • Square • Duct Tape (if necessary) Wood Boards ($16) - http://www.homedepot.com/p/1-in-x-12-in-x-4-ft-Common-Board-458503/100322335 Dowel Rods ($20) - http://www.homedepot.com/p/6416U-1-in-x-1-in-x-48-in-Hardwood-Round-Dowel-10001808/203334068 Instructions: Photos: http://imgur.com/a/Ig3gq 1. Start printing the 20 Dowel Mounts and 4 Shelf Feet. 2. Cut all 5 Dowel Rods in half and sand them to make them smooth, flat, and as close to the same length as possible. 3. Inspect boards and determine which sides will face in and out (and top/bottom). 4. Measure and mark the distance between each tier. Each tier requires a clearance of 10 inches, which leaves 4" extra on the top and bottom. - First measure and mark 4" from the bottom of each board. - Then measure and mark every 10" after the 4 inch mark. (When done, there should be marks at 4", 14", 24", 34", 44") 5. Using the square and tier marks made in the last step, draw horizontal lines across the inside and outside of each board for all 5 tiers. 6. Measure the center points where each dowel rod will be placed. - On each tier, measure and mark 3" from the outside edges. - Do this on both the inside and outside faces of each board. 7. Using a 3D printed Dowel Mount, line up the mount on the inside face of the boards so that it's centered along the horizontal tier lines and dowel center point marks made in the last step. Use the square to make sure the mount is level and trace/mark the mount's screw holes for reference in the next step. 8. Use the drill and 3/4 inch wood screws to mount the Dowel Mounts in their designated positions on the inside face of each board. 9. Slide the 4 Shelf Feet onto the bottom of each board (2 each). Depending on slight variations in wood thickness, you can use a little duct tape to thicken up the inside of the Shelf Feet for a perfect grip. 10. Stand both boards up with the inside faces facing each other, about 24 inches apart. Slide the first two dowel rods into the bottom dowel mounts and push the boards together so that they're snug/flush against the dowel rods. 11. Using the drill and #10 1-1/4 inch wood screws, screw the dowel rods in from the outside faces of both boards using the center point marks made to show where the center of each dowel rod is. 12. Repeat steps 10-11 for the remaining rods moving from the bottom up. 13. Stock your favorite filament!
