CR10S Ball-Bearing Spool Holder

thingiverse

I really liked the [Ender 3 Ball-Bearing Spool Holder](https://www.thingiverse.com/thing:3551666), but unfortunately id doesn't fit on my CTC CR-10S printer, because the holding arm/bracket doesn't have a round hole for mounting. Instead of printing a new holding arm made of plastic, I designed my own mounting stub that would fit into the special shape of the CR10 holding arm. All the other parts are direct copies from the Ender 3 version - except for the little pipe wrench tool, which I created for easier mounting. Especially if you use the long barrel version, it comes in very handy to fix the nut inside the barrel. Besides the printed parts you need two 608zz bearings, A M8 full threaded bolt (11-12cm) and two M8 nuts. In my case - since my local dealer didn't have a full theaded bolt of that length, I used an M8 thread and cut off ~12cm and used an additional Nut to fasten it on the back side. 2021-04-11: **Minor update**: After printing the same for my new Creality CR-10V2 printer, the holder didn't run as swift as on the old printer. The simple solution: two pairs of self printed thin **washers** protecting the bearings from unintentionally touching other parts. The larger rings on the "inside" to protect moving parts from touching the housing, The smaller rings on the "outside" against the nuts on the threaded rod (for details see picture). Now it works perfect again 2021-04-30 **Minor update**. I added a model to print the M8 nuts needed to fix the threaded rod. I printed the nuts with normal resolution of 0.2mm layers/0.4mm nozzle. So all you need to buy for this spool holder is a M8 threaded rod (10-12cm) ad the two bearings, which I didn't want to print for stability reasons. Everything else can be printed.
