Remixed Insert for Modular Prusa Core One Filtration Unit

This is a modified version of @z073’s replacement for the Advanced Filtration System. Variations between filter brands, and even within the same brand, can lead to occasional interference, friction, and potential damage during insertion and removal.

To address this, the recess was enlarged so the filter sits just over 1 mm deeper in the insert. The thin wall with the round cutout was also made slightly thicker to improve rigidity, since that section is now larger. Additionally, the hole position was adjusted to better center the original Prusa fan opening.

I’m not experienced enough to give 3D printing recommendations, but I chose a 0.1 mm layer height and the detail profile in hopes of reducing friction when inserting the foam-covered filter. Repeated insertions and removals while remixing this insert were causing damage to the foam. For normal use cases, the tight fit is actually desirable, so I wouldn’t consider this a defect.

Please refer to @z073’s model page for all model information. I’m sharing this insert because it made an otherwise nearly perfect solution work perfectly for me. I have an original Prusa fan and filter, so you may or may not need this insert depending on the parts you are using.
