Poison Printhead V4 TwoTrees Sapphire Plus/Pro

avaiable on cults3d: https://cults3d.com/en/3d-model/tool/poison-printhead-v4-twotrees-sapphire-plus-pro

This is my own design, inspired by the vzbot printhead. I made this for the Twotrees Sapphire Plus (SP), but I think it will also fit on the Pro. All parts are already oriented the right way, and you do need support for the lowermount and the fanduct.

I made this with a few things in mind. I wanted a light weight printhead and that's rigid. I also wanted to use the Orbiter V1.5, Dragon hotend, Bltouch and 5015 fan. I also wanted to have a belt tentioner build in.

This printhead should solve a few of the problem with previous versions: the hotend is now attached with 4 screws instead of 2, and I already notice more rigidity. I changed the position of the orbiter a bit, so the printhead is now more balanced. I also removed the metal bracket, because it was way too heavy. I kept it for rigidity, but the way it's done now, is lighter, and even stiffer. I did confirm this with the input shaper.

if you have an enclosure, make sure to use a high temp resistent material like ABS, PETG will melt with enclosure.

I'm still testing this setup, so if you find anything that can be improved, please contact me. also any suggestions are welcome. I'm also willing to add other hotends, extruders and probes if you ask for it.

update log:

24-04-2023: added support for the Orbiter V2.0
14-04-2023: improves x endstop mounting
13-04-2023: added mount for sherpa micro

26-03-2023: V4.2 improved the hotend cooling and optimized airflow. I also added something to attach a endstop. I can not guarantee that the endstop works like this, because I use sensorless homing. feedback is ofcource always welcome. because of these changes, some screws had to be changed.

13-03-2023: V4.1 improved belt tentioner and added an extra extention for 5015 fan, so the 5015 fan won't move as much

1x M3x4mm hex bolt

4x M3x6mm hex bolts

10x M3x12mm hex bolts

1x M3x20mm hex bolt

4x M3x25mm hex bolt

6x M2.5x10mm hex bolt

2x M3 nuts

4x M3x35mm standoffs

9x M3x5.5mm heated inserts

standard Orbiter screws

standard Dragon Hotend screws (I think its M2.5x10mm?)

If it gets enough downloads, I'll probably also make a manual for how to assemble it, and add more hotends or extruders.
