• High-temperature 3D printer extruder upgrade or retrofit kit for common 3D printers. This upgrade allows printing of materials at up to 290°C. The barrel is designed in collaboration with Micro Swiss. The finned mounting block has several advantages:

    • Better thermal performance
    • Visibility of extruder (you can remove your stock heatsink – but continue to use the fan)
    • Easy removal of the hotend without disassembling the motor and extruder (tool access between fan blades)


    This kit requires you to disassemble your printer’s extruder and reinstall this upgrade. Instructions will be posted soon.


    Note: the HT mounting block does NOT include an M6 mounting hole, necessary for HICTOP and some other eBay kit printers.


    • SINGLE BUNDLE: High-temp bundle for single extruder kits. Includes entire standard Flexion Extruder kit plus a separate high-temp hotend (barrel, heater block, nozzle). Spare nozzles are: 0.3, 0.5, 0.6, and 0.8mm. This works with the Wanhao Duplicator i3 and similar printers. You will no longer need your stock heatsink with this assembly.
    • DUAL BUNDLE: The best of both worlds! One standard Flexion hotend, and one FlexionHT hotend. The finned mounting block replaces the standard block. Includes a variety of nozzles.  Full parts list:
