Zonestar P802 Right filement spool holder

It is for printer Zonestar P802 2017 with 2 nozzles
I change the default holder which are not long enough to support spool, I found one on thingiverse but the spool was touching the power bank.
So I designed that one with the spool some cm inside the printer so the center of the spool is better aligner with the extruder.
It is for the 2nd nozzle. You can do it for the 1st nozzle, but the logo will be upside down.
It is my 1st contribution, thanks

Edit 2018-03-26: add a new version with 2
