This is a remix of Viktorgleklers Top Spool Holder which you can find here:
This is a absolute masterpiece and was the best upgrade for my Kossy.
But I had to change some parts to make it usable for me.
With this remix I hope to help other Kosselenians with the same problems I had.
First I´ve enlarged the laying area for the spool, because some of my spools have bigger holes so that they were about to fall through.
Second I´ve changed the spool plate with closing it from the lower side and changed the mount for the HDD bearing.
Newer HDDs does not have a complete removable motor, you can only remove the bearing from the HDD, which then have only a small pin for mounting it on the plate (see photos).
Support is needed for the Plate because of the nut holes.
I´ve printed mine with 0,3mm layer height.
