Always had trouble with my part coolers melting and warping from the extruder heat. This is a mount that uses brass tubing as the majority of the nozzle, with a 5015 blower fan mounted on the side.
It's also a much, much smaller profile and mounts on studs that go through the extruder stepper. Wires are run between the space created by m3 nuts with a bushing to protect them from the extruder gear; these wires are accessible with the extruder off, which is also the only time you need to access them.
Printer Brand:
SecKit 3DP Design
Printer:
SecKit SK-Tank
Rafts:
No
Supports:
Yes
Resolution:
0.2mm
Infill:
20
Filament: Atomic ABS Black
Notes:
I use ABS for all parts as the chamber is heated, but the hotend components are the only ones that need to be temp-resistant.
Post-Printing =============Separate parts that are glued can be made stronger.
For the brass part cooler:
It is split into three components that are glued together (ABS makes this easy) so that each section can be printed optimally for strength. The brass tube is cut at an angle and soldered back onto itself, you'll likely need to come up with something locally, but all you need to do is replace the mount section for it.
Bushing to protect wires from the extruder gear.
6mmx4mm M3 aluminum bushings from McMaster Carr fit perfectly in the countersinks of the Bondtech clone.
