Bambu Lab X1C Alveo3d Hepa Filter with extra magnets

I loved the original filter housing from ichmml but struggled with magnet strength whilst the machine was running, often finding that it would fall off part way through a print, which defeats the point of having the filter there.

As there was no f3d file included with the original design I re-created it using measurements from the STL.

Designed to use 8x3mm magnets.

Changes from the original

- Thinner walls, 5mm down to 3mm, removes un-necessary plastic and makes the whole body lighter - Larger openings on the face allows for less plastic during printing
