Ender 3 Spool Adapter

Ender 3 Spool Adapter, fits directly over the stock spool holder, just supports the spool better, it can be altered for any size spool, just resize in Cura, my spool is 74mm internal diameter so i upped my scale to 102% to give it a bit of resistance, fits lovely!

Added a modified spool holder as i found that if you run a side spool setup, it tends to creep off the holder, the modified holder now has a shoulder to prevent this
