P3 Steel Direct Drive Hotend by PerfectFirstLayer

Last crawled date: 3 years ago

This is a modification for implementing direct drive for the P3 Steel. If you have built the AU P3 Steel you will need only two 45 mm M3 screws in addition to the original hardware. I used these:

Secure your PTFE (bowden) tube to the top part of the printer to eliminate jerking in filament when 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 reccomend 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

Added ver. 2 of same design with small changes.
The "platform" for induction sensor made thinner to make more room for sensor threading on top and bottom. This gives more room for the nuts on sensor.
Made the fan duct a couple of mm lower (further away from heatbed) to avoid collisions with bed mounting bolts.
Edit 10/01/18:
Added version with 18 mm hole for sensor, not yet tested. Not sure if it can reach the plate.
