K2 Plus external spool holder

This is an alternative spool holder from Creality for the K2 Plus. I designed a compact version to avoid constantly unscrewing the spool holder from the back.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.What you need it?2x m2 x 10 mm2x m2 o-rings2x m2 nuts2x m3x 15 mm2x Stock m3x10 mmStock black coupler from the stock spool holderStock black spool holder (it's the same spool holder from the K1)*What material is suitable?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.How long take to print?Moreless 5-6 h and
