Download Free 3D Model Micro Driver Magnetic Holder

Summary
Micro Driver Magnetic Holder (version 6) uses add-during-print (15) 2x5mm disc magnets.
My favorite precision bit set came with (3) junky 10-bit holders. I didn’t like that. This holds up to 30 micro screwdriver bits efficiently with easy release.
Prusu .15mm ‘optimal’ settings (modified infill for 2%) for PLA print (large face to the bed).
WARNING. I PROVIDE NO WARRANTY FOR THIS PRINT PROCESS: MAGNETS ADDED DURING PRINT. [USE ONLY NON-FERROUS HOT ENDS & NOZZLES]
VERY IMPORTANT PROCESS NOTES:

VERY IMPORTANT:
This iteration requires a pause during print to insert the 15 disc magnets into the center holders before the lip is extruded above. This can be visually noted by the notches located at the top of where your magnets should rest. ENSURE YOUR MAGNETS ARE FULLY UNDER THE EXTRUDED LAYERS BEFORE PROCEEDING. Once you have inserted the magnets and confirmed that your extruded will not collide with them, resume the print.
Post-Printing
Add the ‘locking’ cap to finalize the magnets position, add a dot of hot glue (or other adhesive) if desired.
