I did not have such big magnets. So I made new openings for 10x5 magnets. Holes are press fit and you do not need glue.I did not have such big magnets. So I made new openings for 10x5 magnets. Holes are press fit and you do not need glue.
I see now that this adapter is loose fit for the MK4 spool holder. Maybe in the future I edit this model and publish it with a better fit.
The author remixed this model.
holes are for 10x5 magnets instead of 20x5.
