Prusa Core One/+/L Dust Protector

These accessories prevent dust or pieces of filament from getting stuck in the Z axis and under the side covers. The shoulders of the PrusaCoreOne_DP_ZAxe.stl files must be directed downwards; they enter the holes in the platform. Two PrusaCoreOne_DP_ZAxe.stl are necessary from each Z axe. The files for the Prusa Core OneL have the prefix 'PrusaCoreOneL_' ; mounting these files is the same as for the Prusa Core One. ACCESSORIES (except for CoreOneL, whose frame is not magnetic) Side protection : 4 x 20mmx6mmx2mm magnets Rear protection : 6 x 20mmx6mmx2mm magnets RELEASE 12/04/2025 Added "Down" text on PrusaCoreOne_DP_ZAxe.stl to install the part in the correct position. 13/04/2025 Slight adjustment (width and angle) of PrusaCoreOne _DP_SidePanel size (parts A and B).
