Bowden Tube Splitter - Dual Extrusion Single Nozzle

Here is a bowden tube splitter I made to experiment with printing multiple filament colors in a single print. I'd also like to try and use regular filament with dissolvable filament or flexible filament. When I printed the first set of files, I thought the hole wasn't big enough, and the turns were too tight. I adjusted for that in the second set.

Here's my current change tool code for Slic3r:

G90 ; Set CNC to absolute mode
M83 ; Set extruder to relative mode

G1 X20 Y230 F7800.000 ; Mo
