AMS Hub using filament buffer / 4 way splitter

My AMS Hub was getting noisy, caused by filament grating on 2 of the input paths. I've been wanting to test replacing this with the A1 hub, but it has been out of stock in the UK for over a month. So I made one, with a mount. I wanted to keep the 4 way splitter compact but from testing longer internal filament paths worked much better/smoother. I've been using this now for over 2 weeks with zero issues. Note: Bambu have changed the screws they supply on the back, you may need to pickup some slightly longer M3 screws. Requires 5 x PC4 M10 pneumatic connectors. Make sure the PTFE tubing goes fully through your fittings as it needs to be fully pushed into the internal channel. PrintingIncluded 3mf file prints the 4 way splitter with a brim @ 0.12 and the filament buffer mount @ 0.20.If you are printing the STL files take a look at the included 3mf file first, and the support blocker, if not careful you will have supports in the filament path.
