Spool Adapter 70mm to 45mm for Spool Holder Ender 3 Pro and Geeetech filament

Here is all my Side Mounted Spool Holder Ender 3 Pro whole setup after a few tests, and this is what worked best for me: Spool Holder: https://www.thingiverse.com/thing:3646853 The spool holder diameter is 2 or 3 mm smaller than the Ender 3 Pro bracket hole, yet it creates no issues at all. I used the short version, glued with two compound epoxy and had to use two of the printed washers for a tight fit. Side Mount Bracket: https://www.thingiverse.com/thing:3505525 It worked fine out of the box using the original Ender 3 pro bracket's screws. I mounted it in its low position, flipping it 180º so the side with the V-Slot clamps goes to the side, not the top. Push Fit Filament Guide: https://www.thingiverse.com/thing:3755454 It worked straight away without any issues at all. With that setup, I managed to mount the spool on the side aligned with the extruder, but the only problem I had was that the Geeetech spool inner hole is too large, so the spool was touching the table. I made an adapter to reduce the spool inner hole from 70mm to 45mm and it now sits about 10mm from the table. I printed the adapter in a rush using 0.28mm layer, 10% cubic infill, two layers and 60mm/s on PLA at 220°C with 65°C Bed and it came out fine!
