Ender 3 Dragon Burner mount (CRTouch)

This plate will let you put a Dragon Burner tool head onto an Ender 3 X carriage (or any printer with the same plate [probably™]). 

Printing:

Something with a higher temp resistance than PLA should be used considering how close it is to the hot end and heatbed (I used PolyLite PETG).

I did normalish settings, nothing special.

0.2 layer height

0.4 nozzle

4 walls

4 top

4 bottom

15% crosshatch infill

I added a solid infill modifier for the center arm that goes from the bottom bolt to the top area.

Printed back down (as loaded into the slicer)

No support needed for the counter sunk holes on the back of the mount.
 

Hardware:

The 4 mounting points to the printer plate use the stock hardware.

2 m3x5x4 threaded inserts (same as are used on the Dragon Burner) if you're not using a probe 6 if you are (make sure they’re flush or slightly sunk in to all surfaces).

2 m3 10mm bolts for the back bottom mounts.

2 m3 35mm bolts for the top front mounts.

2 m3 6mm bolts for the probe (see probe section for details).
 

What I'm using:

Not sure if this is necessary, but it might help someone.

• Dragon Burner tool head from here in PETG
• LDO Nitehawk36
• This board mount
• LDO Orbiter 2.5
• Revo Voron hotend
• Creality CRTouch

Probe:

I designed the mount for the CRTouch, not sure if it will work with other probes, mainly due to the different connector locations. (If you comment detailed dimensions and pictures of your probe, I could probably make one.)

The X offset from the tip of the nozzle is 44mm, Y is 0, Z will vary depending on your hot end and should be calculated manually.

2 6mm m3 bolts work great, slightly shorter should be fine too, any longer will need a custom spacer or a stack of bolt/washers (this might be necessary if your nozzle sits lower than a Revo).

The threaded inserts go in as you'd expect.

Board stuff:

There is a 9mm gap on the top corners of the mount, (from the front of the mount to the back of the tool) so that lots of zip ties and wires won't get in the way of mounting.

As mentioned, I'm using a NH36 and O2.5. I made the mount deep enough so that the board clears the vertical extrusion (with tightly strung wires) with a few mm of clearance when X homing (as pictured). Additionally, this means that nothing needs to be changed to use the stock X limit switch.

The mount should work with other board extruder combos of similar footprint, but I haven't tested anything else. I’ve provided a picture with a ruler to help plan/check if your extruder board combo might clear. If not, I've added a step file of everything to modify as needed.

A possible solution to adding more clearance is to extrude the back of the mount the additional clearance required.

***IF YOU DO THIS, BE SURE TO EXTRUDE IN THE COUNTERSINKS FOR THE HARDWARE ON THE FRONT OF THE BOARD IF YOU WANT TO USE THE STOCK HARDWARE***
