Mmu3 buffer upgrade to rev 4 version b
Hi
I have a mk3s and mmu3, purchased second hand. The original owner had provided extras like some large external wheels, but told me the buffer design had since been refined.
I would like to try to upgrade the Buffer - i think it might be "rev 4 version b".
I'm hoping to find a kit of the non-printable parts to convert the buffer design to a vertical standing with internal wheels (version B). These have smaller bearings to slot between the leaves of the buffer, and printed enclosures which slide inside and clip onto the edge of the buffer.
It looks like i need bearings, shafts and collets. I probably have all the m3 bolts and nuts in the current buffer.
To describe what i do have: the buffer is 5 large black slices with ends that just feed the filament through either side. Its lies flat on the desk.
Many thanks in advance for any advice you might have!
