Ender 3 s1 pro filament spool spacer set

thingiverse

Since my Ender 3 s1 pro has a filament spool rack with bearings in it i made this end-cap and spool spacer set to allow the spool to use the bearings instead of freely spin. You will need 2 spacers and 1 end-cap, Edit: complete re-write of descriptions The replacement end-cap takes the flange off of the end so the spacer can just be slid over without having to remove anything and simplifies the filament change. It re-uses your factory screw and i have found if you tighten it up slightly you can add some resistance to the bearing shaft so if you have rather springy filament that tries to unwind this should help keep the spool stable. The design of the spacers should have them lightly friction fit the factory roller shaft. All of the spacers have roughly a 30 degree angle and should have a slight friction fit on the factory spool shaft. They have a 30mm bore so i don't know but they may fit other machines. The Filament Spool spacer was built off my 250g spools and tapers from 32mm out to 50mm, The 1kg spool spacer was built off the the anycubic 1kg spools i got in and found were a much larger size center bore. It tapers from 67mm out to 84 mm. The medium spacer tapers from 48mm out to 70mm, please let me know if you use this one for 500g spools and if it fits, i don't have any to test it on but just adjusted my sizes to fill the void between the 2 i already made. if you need a slightly different size please comment and i can generate one relatively quickly. Edit: added a smal rack that clips onto the top crossbar to hold the other 2 sets that arent in use.
