Ender 2 Pro spool holder

I've fixed the position of the hole for the Z axis bearing and split the model into 3 separate parts to enable each part be printed in the optimal orientation for strength.

Printed with a 0.2mm layer height. All 3 parts can be printed on the Ender 2 Pro's bed at the same time if necessary.
 

A brim of 2mm may be required when printing the base and stand.

I've now added a second spool holder that has space for 4 608 bearings. Print the octagonal bearing shafts, slide the bearings onto the shafts and then drop them in the slots in the spool holder.
