Introducing FlowHero, a cutting-edge solution designed to enhance the efficiency of 3D printing processes. This indispensable tool simplifies the removal of obstructions in tubes, extruders, and nozzles, eliminating the need for time-consuming methods such as Cold Pulling and component disassembly. Experience a seamless and productive 3D printing workflow with FlowHero, leaving behind the hassle of frequent nozzle replacements.

This is designed to work with 1.5- and 1.75-mm rod of about 150 mm long.

I used these and just cut them in half so I could make 2 1.5mm Rod

As per picture number 2 you need to bend the end of the rod in an L type shape and slide it through the centre and then screw the cap on. I recommend using lubrication on the thread, but I do that with all my plastic threads.

If you like the design and wish to contribute.

For the Grip I used Makerlab TPU and glued it on and it ended up looking fantastic. 3D Printer Filament - 3D Printworx
