The file 'Twin Extruder Mounting Brackets For Ender 3 3D Printer Model' is (stl) file type, size is 69.3KB.
This will allow mounting of 2 extruders, including motors, on the existing mounting point on the ender 3 gantry.
You can use existing stock extruder, clones, and the all metal clones. I used 2 all metal dual-gear versions, which are a bit "taller" than the stock, and allowance has been made for this. (This particular extruder is good for TPU as it has very small clearances).
Mount as shown in the pictures.
I will soon be adding my hotend mounting choices, for an E3D Chimera+ with volcano blocks and nozzles.
I printed this in PETG with 80% infill.
