BIQU H2 filament cutter with integral strain relief and ECAS mount

Due to differences in how I mounted my Biqu H2 I needed to add strain relief to the filament cutter. I also added an ECAS mount for reverse bowden, I don't trust sticking PTFE tube in a hole without teeth. It's a hack job done in 3d Builder so I can add an ERCF to my heavily modified Ender 3 but it prints successfully with support and doesn't interfere with the cutting action of the original mount.

Use the rest of the parts from the original model and assemble per the instructions.

Added strain relief riser and ECAS mount to the filament cutter base.
