P3 Steel Direct Drive Hotend

thingiverse

This is a modification for implementing direct drive on the P3 Steel. If you have built the AU P3 Steel, you will only need two 45 mm M3 screws in addition to the original hardware. I used these: http://www.thansen.dk/product.asp?n=511490482&pn=511491043 Secure your PTFE (bowden) tube to the top part of the printer to eliminate jerking in filament when the x-axis moves. This can be done with cable ties and a glue gun (see pictures). As extruder, I used this: http://www.thingiverse.com/thing:754217 by Phil_Maddox. I recommend printing this in PETG or ABS since the fan duct comes close to the hotend. Things needed to make this: PTFE tube 30 cm PTFE tube 10 cm Nema 17 stepper motor Induction probe Radial Fan 50 mm E3D V6 Universal hotend full kit 2 x 45 mm M3 bolts (40 mm might be enough) 3 x 10 mm M3 bolt 3 x M3 nuts Cable ties Edit: December 7, 2017. Added version 2 of the same design with small changes. The "platform" for induction sensor was made thinner to make more room for sensor threading on top and bottom. This gives more room for the nuts on the sensor. Made the fan duct a couple of mm lower (further away from heatbed) to avoid collisions with bed mounting bolts. Edit: October 1, 2018. Added version with an 18mm hole for sensor, not yet tested. Not sure if it can reach the plate. Print Settings: Printer Brand: RepRap Printer: P3 Steel Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 25% Notes: I used support for the base part overhang. Might not be needed.
