3mm filament Orbiter Remix for e3d tool changer

Sharing my model for a 3mm Orbiter based direct extruder adapted to work on the E3D Toolchanger. I used the excellent base Orbiter extruder from w1ber (https://www.thingiverse.com/thing:4643022) and modified the filament path for 3mm. The base accomodates a 6mm PTFE tube that leads directly into the standard e3d v6 extruder mounted underneath. To keep it tight, the tube length is cut right at the length before assembling. As hotend holder I use my ToolChanger E3D V6 hotend mount (https://www.thingiverse.com/thing:3843247) below - printed in CF PETG it proves rigid enough for repeatability. The Part cooling fan is also published there. The hotend is a bowden original e3d V6 3mm. The files have been printed in Nylon with a HP MJF machine, they hold up very nicely (~100h printing so far). The base is made to accomodate M3 inserts. The base extruder bits (gears and shaft) are coming from the kit sold on Aliexpress, and I replaced the filament wheels with the 3mm inner diameter 8mm Drivegear kit from TriangleLab (https://www.aliexpress.com/item/32950159362.html) All in, it works extremely well and provides a neat way to print 3mm filament with effective cooling. The only alternative I know of for 3mm on Toolchanger would be the Aero extruder, and I couldn't find a solution to mount a part cooler...
