Grado Headphone Earpad

thingiverse

Grado headphones are truly awesome, but the foam ear pads break down at an alarming rate. Determined to find a solution, I decided to experiment with NinjaFlex rubber filament. To my delight, the fit is absolutely perfect on my circa 1994 SR80s. Despite potential size variations over the years, they share similar shapes. The comfort of this design falls short of original foam quality, yet I believe fine-tuning build parameters could soften them significantly. **Print Settings** * **Printer Brand:** MakerBot * **Printer:** MakerBot Replicator 2X * **Rafts:** No * **Supports:** Yes * **Resolution:** 0.16 * **Infill:** Experiment with settings, but 10% is a good starting point. **Notes** I printed this in NinjaFlex using 4 layer top/bottom and 3 layer walls with 10% infill. These parameters result in robust prints, but they can be somewhat firm. I recommend trying 2 layer walls and reducing the infill to 8%. Ensure at least a 0.5mm horizontal space between supports or it becomes incredibly difficult to remove. It took around 8 hours for each pair to print at my standard speed settings for NinjaFlex. **Post-Printing** NinjaFlex makes printing relatively easy if you've already got it running smoothly. Removing supports can be a bit tricky, so keep at least 0.5mm horizontal space between them and leave a 2 layer gap on top/bottom contact surfaces. I used Autodesk Inventor to create this design model. Using calipers and simple sketch and revolve functions took around 15 minutes to complete.
