I loved the design/concept of the spool holder designed by edgarp (https://www.thingiverse.com/thing:2431355), but found the edges very hard to grab when trying to take the holder off of the filament spool. Using the dimensions on their page I remixed it with the following changes:
- Added 5 mm of flat space on the end of both nut and base.
- Added notches in edge for easier grip
- Increased the overall length of the base piece by 6.5 mm to better fit the size of my CR-10S spool holder (32 mm diameter and 82 mm length to threads). This allows the stock spool holder nut to secure this addition in to place.
Please Note: With the increased length of the base both the stock CR-10 spool holder nut and the nut of this piece cannot be tightened as tight as possible. One needs to be slightly loose to allow the spool to spin freely.
If you have any comments or suggestions please let me know!
Update 1: Added STL for Ender 2 spool holder. The only changes from the CR-10s spool holder is decreasing the length to 78 mm from 82.5 mm. The nut is the same for both spool holders, only the base will change.
Update 2: Added STL (BaseV3-with-internal-nut.stl) for new and improved spool holder base that works with both CR-10S and Ender 2. This version includes internal threads that replace the stock spool holder nut so you no longer need to use the stock nut to secure the base onto the Creality spool holder. The length of the new base is 81 mm.
