Spool spacer for cheap filament

This was designed for the off brand cheap pla spools that have an inner diameter of about 70mm it is two halves that just go together on the shaft .

Note I did not like the ender 3 spool shaft as it was so i cut the lip off with a hacksaw, then drilled a small hole through it and used my smallest Alan key as a pin to hold the spool on. I doubt this would fit without modifying the shaft.
