I was waiting for months for Anycubic to send a replacement print head for my Vyper, as of 10th May 2023, I still haven't received it, initial support ticket was lodged on 21st January.

I bought a cheap 3DSWAY V6 Volcano hotend of AliExpress, as the Vyper can't do manual bed adjustments I needed an adapter to fit the stock strain gauge. There's a few other Vyper V6 adapters but none of them would fit the 3DSWAY hotend bowden tube fitting.

You'll need to print 2 and they DON'T need to be mirrored. You'll also need some M3 5mm outer diameter, 3mm length Brass inserts. I used these. 

Make sure you use the knurled inserts rather than the injection molded style ones, they just don't hold enough to get a good grip on the hotend.

Print with 0.2mm layers, 999 walls in PETG or other material that can handle the ambient heat from the bed and hotend, I use a janky enclosure made from the cardboard thick sheet that came with our new king size mattress.  I printed it with the top mounting holes up with supports and blocked the supports in the M3 holes.
