About this model

Here's our cardboard spool adapter ring generator. Open the .f3d files in Fusion 360 and adjust as you please. We primarily use Inland spools that are cardboard but I'll add to this if you'd like to provide a diameter in millimeters. We print ours in PETG which is a bit more durable and flexible to go on and off spools than PLA is. Types of Ring SurfaceThese are experiments. At times we find the rim edge is too slick. Ribbed and V-groove take much longer to print.Smooth - no pattern (normal)Ribbed - circular extrusions on the outer surfaceV-Groove - v-groove pattern on the outer surface - Spool SizesThese 8" calipers are great for measuring spool outer diameters but a decent tape measure will work too.SPOOLCardBoardDia Inland PETG / PLA 199.6mm Future options (let me know!)
