Yet another filament spool

thingiverse

I had some massive spools of high-quality PLA filament that weighed in at 3kg each, requiring substantial and robust external holders to securely fasten them. Unfortunately, my simple and weak CTC printer was unable to accommodate one of these large spools. Luckily, I had some PVC tubes nearby, which I quickly used to design a joint and a plug to complete this basic filament spool holder using OpenSCAD. The design could be easily modified in OpenSCAD to accommodate different tube inner and outer diameters, making it highly versatile. However, since PVC tubes can be slightly imprecise, some trial and error may be necessary when determining the optimal lengths of the tubes based on the spool diameter and depth. To assemble this spool holder, I needed to print two joints and four foot plugs, as well as five pieces of tubing: one for the center and four for the legs. My specific spool and holder measurements were as follows: Spool outer diameter: 300 mm, Spool inner diameter: 55 mm, Spool depth: 115 mm, Tube outer diameter: 32 mm, Tube inner diameter: 28 mm, Center tube length: 125 mm, Leg tube length: 250 mm. When printing these parts, I used the following settings on my CTC Bizer printer: Rafts: Yes, Supports: Yes, Resolution: 0.2 mm, Infill: 20%.
