Herman Miller Aeron Chair, a popular office seating option, doesn't come equipped with a headrest, prompting one user to create their own DIY solution - a makeshift headrest cobbled together from readily available parts. Though it may not be visually appealing, this homemade alternative prioritizes comfort and functionality above all else. The DIY headrest's build is remarkably straightforward, utilizing an M8 smooth rod and an M8 coach bolt as its core components. Supporting structural elements include M4 cap heads, M4 wing nuts, and M4 nuts. As per the model files provided, users can determine precise lengths of each component by closely examining these detailed blueprints. Of paramount importance for this project is the use of flexible PLA plastic to mimic the distinctive weave typically found on authentic headrests. In terms of 3D printing specifications, key components like the MAIN CLAMP and JAW require an absolute level of quality; print these with a solid 100% infill for unparalleled strength. Notably, users will need to apply significant post-print modification to the JAW by filing down its surface due to PLA's inherent expansion differences when compared to ABS. Furthermore, a calculated design choice was made regarding infill percentages for the rest of the parts; this DIY headrest utilizes 50% infill in ABS to achieve optimal balance between strength and weight. A noticeable consequence of printing multi-type plastics together is shrinkage variance – model files account for potential disparities but do offer an acceptable margin, providing enough leeway for adjustments post-print.
