Donor Spool Holder for Large Spools

I've used the excellent KYZ Pasta Lite respooler to respool filaments. I tried to use it with a 3kg spool, and it didn't work as the spool was too big for the donor base (it rubbed on the frame) , and the spool wasn't secured because the screw column was too short. I re-designed the base so it could be mounted on a board away from the rest of the frame, and extended the spool holder and spool tower so the bigger spool would fit securely.
