Use these 2 little buckets on the underside of the PEI build plate at the front lifting tabs.

***UPDATE***

New “Flush Magnets" models uploaded.

So after printing and installing these buckets I have decided to not recess the magnets below the top layers. But rather move the magnet inserts to be flush with the top of the print. They just are a little weak to make good contact when they are recessed. They stay on during the print as is but I think a stronger attraction if the magnets to the plate is better. I will be updating it rather adding 2 new STLs with that change. 

 

These are intended to catch the purged filament from the multi tool extruder when it primes at the beginning of each print.  They attach to the underside of the lift tabs on the PEI plate with magnets that are inserted during the print.

Print with whatever material you like with whatever infill and layer height you'd like.  The magnets are 6mmx3mm and placed beneath the top layers of the print at 1.2mm.  So you'll have to pause the print at the top of the insert holes to place the magnets.

The 3mf file attached is sliced in PrusaSlicer on my MK3S with MMU3 using extruder #5 using Prusament Galaxy Black Filament.  It also has the rear face of each bucket marked with a “R” and “L” respectively.  Right and Left are taken from the perspective of looking at the printer from the front.

Since I'm still printing the buckets I have not tested them for fit or functionality, but I will post photos as soon as the print is complete and I have attached it to my XL.  And I will upload revised STLs as needed.
