As it happens with the Creality K1, you only need to remove the black spool holder when not in use if you like it.

It made a test print (benchy) and works awesome without any issue like the stock one.

It has the logo outside.

You can remix it if you like.

2x m2 x 10 mm

2x m2 o-rings

2x m2 nuts

2x m3x 15 mm

2x Stock m3x10 mm

Stock black coupler from the stock spool holder

Stock black spool holder (it's the same spool holder from the K1)*

ABS/ASA infill min 15% (if you use PLA/PETG increase it min infill 30% or your spool holder will going to break it by the weight of the spool- not recommend it)

Does it need support?

Yes, only in the heatbed with tree supports

(*): You can find a tons of K1's spool holders here if you don't want to use the stock one.

Moreless 5-6 h and it depends about what settings you stablished

First remove the 4 left M3 screws from the back cover of the K2 Plus (where is marked to install the stock spool holder)

Second take out the 2x m2 stock screws to remove the black coupler and reinstall it in the new spool holder, in the same way like the stock spool holder, with the larger m2 screws in the upper list and fix it with o-rings and nuts.

Third take out, turning the back cover, the black spool holder from the stock spool holder and leave it in one side.

IMPORTANT: Keep the original screws (except the stock 2x M3x10mm), the black back cover of the spool holder and the stock spool holder inside a plastic bag to avoid lost it

Fourth install the spool holder using 2x M3x 15 mm in the upper hole and the below hole and use the 2x stock M3x10 mm (the same screws that you use to install the stock one) for the middle holes.

Last take the black spool holder and install it.
