M3D spool holder 1kg

I bought a 1kg velleman pla spool and I needed a way to use it. This is currently Printing so I can not guarantee its function yet.

Uses
4pieces of 688 bearings and 5 pieces (approx i have not measured them yet) 10cm lengths of M8 rod.

I make continous changes to it.

The hub and mount I have now printed and they work fine! The rodmount is printing right now. Hopefully it is ok!

Everything works! The internal filament guide (the black thing) was a bit in the way so I decided to cut it off since I don't use it.. DONT!! There is 16 cables in there as well.. It took me 8 hours to disassemble the entire printer and find out which cable should be soldered to which cable.. The printer is now back up and running and it works perfect but it was not a good idea..

Have been testing it now for 50 hours or so and it works great! I will change the woodsticks (pens) to alu soon and that will make it more sturd
