Ultimate Miata Door Bushings

Please see https://www.printables.com/model/970292 for the updated and much superior dual durometer design

After testing numerous printable door bushings, I found most to be unsatisfactory. They either didn't fit properly, required sanding, were challenging to print, or lacked sufficient adjustability. 

These solid bushings address these issues by offering a perfect fit for a 10mm socket, regardless of bolt placement, with some good room for adjustability. The bottom surface has been slightly chamfered to prevent elephant foot.

No, they do not increase chassis rigidity. Yes, they do reduce NVH in most cases, which gives the feel of having a “stiffer” car.  They do also add quite a bit of lightness over the OEM ones (~70g reduction in total).

STEP and F3D files also included, feel free to remix

The “_Resin” files have been slightly modified to prevent cups when printing flat on the bed

Print in high hardness TPU for best results
