Does anyone know anywhere in the UK where they do 3D printing of the rear baffle as I saw on the PF site several versions but the best being the one with the square cut out of the baffle. Seems there was someone doing it a few years back but in the US.

Thanks.

Just a follow up, I did a little video yesterday

Basically I bought another rear baffle from JPTechnical for 16 delivered. Did the same as the first in terms of splitting the 2 parts of the rear baffle but as this was a spare I took a metal file to the lip whilst it was on a wooden work bench and as it's not thick or industrial metal, it filed down easy and quickly. A few goes with the file gently smoothed the surfaces. Then it was a case of washing thoroughly to remove any metal shards and drying before using a black sharpie on the shiny metal and glueing back together.

Here is the rear baffle back in and with no lip.

That's pretty awesome Gareth, I'm surprised it wasn't so much work with the file considering I read a comment a while ago saying it was quite a tough metal. Perhaps the user was using a tool without the required hardness.
