This is a handle you can use if you want to create your own NoClogger device https://noclogger.com
This handle is designed to take a 1.6mm rod (the NoClogger version uses a 1.5mm rod).
You will need a 1.5mm to 1.6mm diameter rod, with the length depending on the length from the tip of your hotend to your filament insertion point. There is 1.5mm x 30mm deep hole in the design to make the insertion of the rod easier, but i heated my rod before inserting it to make it easier.
i printed this in ASA, with a brim but i don't think its needed.
Print orientation is as pictured.
just in case you are having a hard time sourcing your rod here's a link:
