Replacement Drawer Roller

Summary A friend at work had an old drawer with a broken runner wheel. The manufacturer no longer makes them. What a perfect situation for a 3D printer! I modeled the existing wheel in Autodesk's 123D Design using nothing but cylinders of various sizes, using the Combine/Merge and Combine/Subtract tools. I chamfered the edges of the wheel, but realized after printing the first prototype it wasn't enough, so added more and the second prototype looked good. I added the screw pocked on one side so when screwed to the bracket, the head will have some recessed room to hide in. The wheel measures 28.2mm in diameter, with a 7mm hole in the center. The projection on the side is 5.26mm.Print Settings Rafts: NoSupports: NoResolution: .2mmInfill: 100% Notes: Printed with Taulman 910 Alloy Nylon, so it should last forever - How I Designed This: Designed in 123D Design. Started with a cylinder the correct wheel dimensions, chamfered the sides, added another cylinder on one side for the extension. Used a 3rd 7mm cylinder to cut the screw hole through the center and a 4th 10mm cylinder to carve out the screw pocked on the opposite end.
