CORE One+ Spool holder with 6807 bearings

Update:
Added parts for 2kg spools.
-"spoolholder_center_2kg"
-"spoolholder_tube_2kg"

This spool holder uses the original bayonet fitting "puck" from the CORE One+ spool holder. 

When this one is printed and assembled, it can easily be removed and replaced with the original parts when needed.

Hardware needed:
-2x 6807 bearings (35x47x7mm).
-2-4x m3x20mm bolts (using two is more than enough, but four can be used).
-Replacement O-ring for the original spool holder.

Print one of each part.

Assembly:

-Push O-ring onto the end of the "spoolholder_center" part just like the original.

-Push one 6807 bearing onto the "spoolholder_center" part (from the bayonet fitting end). It should be flush with the ledge where the O-ring rests.

-Push one 6807 bearing onto the "spoolholder_cap" part.

-Use 2-4x m3x20mm bolts and attach the "spoolholder_cap" to the "spoolholder_center".

Now, Inspect the "spoolholder_tube". On one end (which was at the top when printing) there is a tiny groove.

This should be facing inwards towards the printer when mounted. This is important since the original spool holder "puck" is slightly tapered. 
The printed tube is thinner on the side with the tiny groove to make sure it fits over the "puck".

-Take the "spoolholder_tube" and push it onto the assembled spool holder. (Yet again, make sure it's oriented correctly. The smooth end should be going towards the "spoolholder_cap", and the end with the tiny groove should be pointing the same way as the bayonet fitting).
It should be fairly snug when sliding over the bearings. Keep pushing it until there is around 1mm left to the "spoolholder_cap". It shouldn't rub against the end when rotating.
(If the "spoolholder_tube" is too tight over the bearings, you might have to print it ever so slightly scaled up. It all depends on your tolerances when printing)

Now it's ready to be attached to the original spool holder "puck".

The cap has an arrow above one of the bolt holes. This should be pointing upwards when the spool holder has been locked into place.
When inserting the spool holder, orient the arrow at around 10 o'clock, push it all the way in on the "puck" and twist it clockwise until it locks into place.

Put a spool on and then slide the "spoolholder_clip" in from the top until it clicks into place. 
The tab for grabbing it should be facing outwards.
