Heatset insert for H1

I'm a sucker for heatset inserts, and I figured if you're occasionally maybe opening the device, might as well put a heatset insert in there, remove the chance of breaking plastic threads.

This remix was made with CNCKitchen's short m3 inserts in mind. Its worth noting that I havent printed it yet, and CNCKitchen advises 1.6mm walls around an insert, and we're under that value, so I do need to test if this remix actually works optimally.

There are four variants, stock, stock extended, reduced branding, and no branding from my other remix.
