Filament Colorizer Edding Permanent Marker

thingiverse

So my seven-year-old comes up to me and says, "It's a shame we can't 3D print in color." She asks, "Why can't we just color the filament before it melts?" I love my little tinkerbell. To my surprise, others have made similar things. This is my version. I don't need crisp colors, so a single line on the side of clear filament does fine. It's designed around Edding 3000/3300 permanent markers, but you could easily make adapters for any other marker up to about 16mm thick. The adapter has hooks to hold the filament clamped, but I found friction was enough. All the parts have been printed in PLA, with a 0.4mm nozzle, 0.3mm layers, two walls, four bottom/top layers, 25-50% infill, and no raft/brim/support. Print Settings: Printer Brand: RepRap Printer: Kossel Rostock Mini Rafts: No Supports: No Resolution: .3mm Infill: 25-50% Notes: These markers work better when held upright! How I Designed This My seven-year-old daughter had a great idea, and she asked me, "Why can't we just color the filament before it melts?" She said, "It's a shame we can't 3D print in color." Her question sparked an interesting discussion. I decided to design something that would solve this problem. I designed an adapter that attaches to my Edding 3000/3300 permanent markers. The adapter has hooks that hold the filament clamped in place, making it easy to attach and detach the markers. The parts were printed using PLA with a 0.4mm nozzle and 0.3mm layers. I chose this material because it's strong and durable, perfect for holding the weight of the markers. To print the parts, I used the following settings: Printer Brand: RepRap Printer: Kossel Rostock Mini Rafts: No Supports: No Resolution: .3mm Infill: 25-50% I also added a note to remind myself that these markers work better when held upright. My daughter is thrilled with the result, and I'm proud of her for coming up with such an innovative idea.
