Removed those useless sun visors? This model is an easy-to-print block-off plate that fits Mk1 and Mk2 MX5/ NA and NB Miata.
 

It uses the stock hardware to install and only takes 2 minutes.
 

The models in the pictures are printed with a variable layer height but 0.2mm would work great. The pictured model has also been sanded, primed and painted.
