Anycubic i3 Mega Direct Drive - Titan

thingiverse

Direct drive assembly uses the stock Anycubic carriage plate for Titan or equivalent extruder. I used the TriGorilla, available at [Amazon](https://www.amazon.com/gp/product/B07L1NM3KP), which comes stock on the Mega S. Many clones are available, such as this one: [Aliexpress link](http://s.click.aliexpress.com/e/_sfai87). I don't have direct experience with this clone and can't recommend it. You can also use the original E3D Titan extruder, probably the ethical thing to do. The Titan works with the E3D V6 or equivalent hotend. I used the Trianglelab version, available at [Aliexpress](http://s.click.aliexpress.com/e/_sW6psX), which has been rock solid. The part cooler is a slight remix of Thingiverse's 2815388, a remix of Thingiverse's 2765158. The belt holder is a remix of Thingiverse's 2838383, made to mount directly to the i3 Mega carriage plate. Design uses the standard micro fan that comes with the V6 hotend mounted facing forward on the heatsink. **Parts List** * 12V all metal E3D V6 hotend or clone like this one: [Aliexpress link](http://s.click.aliexpress.com/e/_sW6psX) * E3D Titan extruder or clone like this one: [Aliexpress link](http://s.click.aliexpress.com/e/_sfai87) * While the stock extruder stepper can be used, I highly recommend using a slimmer, lighter pancake stepper motor like this one: [Aliexpress link](http://s.click.aliexpress.com/e/_sEi8sT), which works well with the 3:1 extruder gearing. * 2 x M3 14mm * 2 x M3 8mm * 2 x M3 18mm * 6 x M3 nuts * 1 x M4 22mm and M4 nut for fan * PCB board reuses the 3 stock M3 screws. * GT-2 6mm belt (the stock belt is too short by about 30mm) * 1 x 5015 12V radial fan like this one: [Aliexpress link](http://s.click.aliexpress.com/e/_sMGMHV) **Notes** When printing the part cooler, make sure supports are only used on the outside of the part and not the inside. This will likely happen when auto-generating supports (S3D will do this). A primary objective of this design was to retain the same printable area as stock. You will need to modify your "Home" offset for the Y axis approximately 10mm to accommodate the new nozzle location. This can easily be done in the EEPROM using the M206 or M428 commands. **Remix** There have been lots of requests for a BL Touch to be added. Feel free to remix and please leave a comment if you improve on this design. [Source File Download](https://a360.co/303MnXE)
