3D model description

NOW ALSO S ORBITER 2.0 AND SHERPA MICRO!
ADDED FOR DRAGON VULCANO!

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 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 me. also any suggestions are welcome. I'm also willing to add other hotends, extruders and probes if you ask for it.

update log:

27-09-2024: added Superfly extruder top mount

26-06-2024: added for the vulcano dragon hotend, and made new ducting for it.

03-06-2024: changed the mounting of the fanduct. it now uses one of the M3x3mm heated inserts, and adifferent fan brace

11-10-2023: enhanced the hotend cooling. I personally had problems with heatcreep when i used an enclosure and wanted to print pla or petg. I've added some fins to reduce the turbulance that is created by the 4010 axial fan. I also added some heated inserts for the 4010 axial fan and the bltouch (check the parts list)
18-07-2023: added for revo voron hotend.
24-04-2023: added 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. 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

Needed hardware:

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 M2.5x5mm hex bolt

2x M3 nuts

4x M3x35mm aluminum standoffs

9x M3x5.5mm (4.5mm OD) heated inserts
2x M3x3mm (4.5mm OD) heated inserts
2xM2.5x3mm (3.5mm OD) heated inserts

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

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

sub 12 minute benchy. could be faster (i did it in minutes), but forgot to change de decel to 30k.

3D printing settings

like I said, I print this in ASA/ABS, but PETG should be fine if you don't have an enclosure. 0.2mm layer high works fine for me.
