Masterspool - Twist and Lock wider hub
thingiverse
This modification of the hub by 3d-workshop fits spool refills that are just a little too wide for the standard spool. You can download the sides, reload key, and the original hub from here: https://www.thingiverse.com/thing:2823667 Update: A new hub is now available that's slightly smaller for Wanhao Duplicators or Monoprice Maker Select since the first one was too big to fit on the stock spool holder. Pro tip: Using the smallest possible hub is key. If it's too large, your filament won't be tight and will get messy and hard to print. Only use this mod if the original hub is indeed too small.
