I liked the idea of a removable magnetic wall panel. However, I didn't want three of them, just the right-hand side. This side is often the hardest to access from the front when you have an issue with the filament feeding into the print head. I modified the Fusion360 model to keep the rear panel fixed as per the original LACK enclosure.
I also made the magnets a larger diameter of 8mm x 3mm instead of 6mm x 3 mm.
Slicer projects include the parts from @FlybyTom with modifiers for the bigger magnet. I've included the modified Fusion360 model as well.
Thanks @FlybyTom!
The author remixed this model.
