Miata NB ('99-'05) MegaSquirt mounting brackets - MSPNPPro (MS3)

The MS3 does not mount to the stock ECU mounts on an NB Miata (mine's a '99).

Recommend printing with:

• ABS filament
• Fill density=30%+
• Perimeters=3+
• With supports

These originated from Risi_turbo's MS2 mounts from https://www.thingiverse.com/thing:3849892

The MS2 has the options port in a different place than the MS3, so the bottom bracket in that model doesn't work for the MS3, because that model would cover the options port. Cross referenced from byteVenom's remix, ZeSneakyNinja made an MS3 version: https://www.printables.com/model/176470-01-05-miata-ms3pnp-mounting-bracket

That fixed the options port problem for the MS3, but I found on my ‘99 Miata that the clutch pedal might contact the bottom bracket. So here I’ve made a remix of the bottom bracket, where the main difference is I moved the ECU to the right by 0.75 inches & added some supports for the difference. I'm expecting this should work on any NB Miata, but have only tested it on mine.

On the top bracket, I also thickened some parts & added rounded corners for better load distribution (similar to ZeSneakyNinja's bottom bracket mods).

Installation:

• Zip tie the printed brackets to the MS3
• Use the same two flange nuts as the stock ECU mounts

Once the nuts are tightened, the MS3 should be firmly in place, and a depressed clutch pedal should not make contact with the lower bracket or MS3.
