Filter chamber opening key-tool for NanoHack anti-virus mask
Description
this is an opening tool for the filter cap for the NanoHack (thing:4231069) type mask filter cover. I suggest to lightly apply some lubricant like techical vaseline or even some sunflowe oil on the thread of the cap but anyway this tool helps a lot some time. Here is a youtube video of the previous version (the neck of the handle was too narrow and infill was too weak so I had to make this version) https://youtu.be/8ZnYjqaa_GQ If you found my design useful or inspiring and would like to buy me a cup of espresso you are welcome to tip me: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=U25V96GZNVL3N&source=url Thank you!
