Kobra 3 8 color filament hub v5

This is the v5 design (and hopefully the final) design of my 8 color filament hub for the Anycubic Kobra 3 Combo.

This requires use of spring and collets.

the collets need to have small flanges, these can be sourced from 2 stock Anycubic 4 color hubs or from other vendors.

I have found that the BondTech collets appear to be the same as what Anucubic use, but i havent received my package of them yet so the below link is provided for a potential source only and does not indicate that the items received will be the correct ones.

you will also need springs, once again these can be sourced from 2 stock Anycubic 4 color hubs or from other vendors

the stock prints have a diameter of 7mm, an uncompressed length of 11.5mm with a compressed length of 3mm

you can go with marginally longer springs, but you should get as close as you can.

For guidance on fitting the parts together please see the following video
