I have used your spool holder for 8 months now, but encountered a few problems. Especially spools that are not flat inside, but have edges and are hollow inside, does not fit this design. I then printed a cylinder to fit and roll on top of the ball bearings. This worked great, but I experienced that the stock shaft is a bit too short for some spools or the hole in the spool is too little to fit over the cylinder.
So I ended up designing a new shaft, and include the ball bearing in the shaft, but keep the rotating cylinder. I posted the new and (for me) better version here: https://www.thingiverse.com/thing:3408308

Creality CR-10S replacement ball bearing spool shaft

I'm impressed with the design. The fittings are a bit too tight, but manageable. I had to remix to adjust to the size of bearings I had lying around and made one other change. Since the spool sits high in relation to the CR 10S' spool holder axis, I was able to changes the spool "lock" that keeps the spool from sliding off. Mine is a flange that fits the holder, but it's smaller than the spool opening. I added a tab that, when turned upward, matches the height of the bearings. This allows me to remove the spool. With a 180 degree turn of the tab downward, the tab now sits low, going beyond the bottom of the spool's hole, which locks it into place. Thanks for a very clever, almost friction-less holder.

Love the design. Anyone have this in 32.3mm shafts before I try to make it? Looking at printing one of these for the CR-10S. Thanks all.

I just made one to fit 32mm & 30mm, but uses larger 608zz bearings
Currently upto v4.0 which should be the finial version (printing now)

My first one broke because it was to tight so i print it again with TPU filament. smooth af =)

I think there is fundamental issue with this design which is that it works with tight tolerance but depending on where Creality source its parts you can have significant diameter changes on the tube. The one on my CR-10S is almost 0,4 mm larger that the one on the CR-10. TPU seems a nice way to overcome this !

Use a bench vise and 6mm socket to press on the bearings, and then push everything together using the bench vise. Pushing on the seal area (middle) of the bearing may ruin it, so don't. Thanks for sharing a great design!

Hi, my axis diameter is 32.2mm. can you create a bearing support for this size of diameter? Thank you.

Great idea but suffers from some size issues.

my shaft is 32mm is there a way you could help out? I do not have fusion 360 and do not know how to use it. any help would be appreciated

THANX

As a point of reference, 608 bearings are very common for the current fidget spinner craze, and lots of people would have that size around, rather than 625's. I have no idea how they compare, but I'm guessing 608's are slightly smaller.

Brilliant idea. I may try it with 608 anyway!

I just made one tthat uses 608's, for 30mm and 32mm holders
Let me know if you want a 608 to fit a smaller size

I was also hoping this would work with 608's since I have those on hand as well!

Did the 608 bearings work for you?

The size of the piece that is supposed to hold the bearings is improperly sized. 5 mm diameter bearings don't fit! The posts are 5.14 mm in diameter not 5 mm. And if the whole piece was scaled down in size then its too small to snap onto the metal pipe! Frustratingly useless.

Obviously, I used a hammer!
;-)

The parts were a little tight for me as well.

Obvisouly done on purpose. You press fit the bearings and they are properly held in place. Ask 3DFreezeMe how he managed to install his bearings for his make...

Thanks for sharing! Just printed a set.
The bearings used are the 625 type.

I just added the bearing reference in the description. Thanks for the information.
