NinjaFlex Tire, tread, traction

thingiverse

I've created this file to add traction to my helicopter's wheels. I've printed them with grass green NinjaFlex, a process that takes about half an hour per band due to its thickness of roughly three centimeters. To guide the flexible filament into my extruder, I used a 9mm long piece of a BIC ball point pen, where the plastic part is devoid of ink. This setup works well on my Printrbot Simple metal. Below are the print settings that I've found to be quite effective and might be helpful for others. Print Settings Rafts: No Supports: No Resolution: .18 Infill: 10 percent Notes: To get the best results, make sure to set fill levels at 10% and speeds at 20 mm/s. Also, ensure your print temperature reaches 210°c, while keeping the heat bed at 50°c. It's essential to adjust the flow settings to 120%, retract the filament, and turn off the fan. Printing with a longer skirt helps establish the right flow for this application as well.
