Minimalist Heat Insert Press MGN9H 300mm remix

Remix of SNASA's Minimalist Heat Insert Press — MGN9H 300mm Rail Version

This is a remix of SNASA's Minimalist Heat Insert Press adapted to use a MGN9H linear rail instead of the original LML12B. I redesigned the arm block and carriage mount to fit the MGN9H. It's not a perfect 1:1 replacement geometry-wise, but it's close enough and works well in practice.

I used a 300mm rail instead of the original 200mm — gives a bit more travel, which is nice.

Just print the two parts from this remix, then print everything else from the original and follow SNASA's assembly instructions — just swap the rail.

Changed hardware:

• 1× MGN9H linear rail, 300mm (instead of LML12B)

Print settings:

• 3 walls
• 25% gyroid infill
• Anything in that ballpark should work fine
