Changelog Iris box v1 - Blade_v3

Some users have reported issues with sliding at the end of travel. The file "Blade_v2" has been updated to the new version "Blade_v3."

The mechanism is now much smoother thanks to the following modifications:

- The blade guide is now linear instead of curved.

- The blade thickness has been reduced by 0.2mm, increasing the clearance between the parts.

With these two improvements, the mechanism will always be smooth, regardless of the type of 3D printer and/or filament used, making the design stable.
