This is a Covid19 "No Touch" Door Opener tool that slides open/close.

It has resistance to closing. The slide lock mechanism from mishkin's "maker knife clone" locks, unless the user pull/push the thumb ring. It's a fantastic mechanism that prevents accidental closing. And it is surprisingly durable.

It doubles as a fidget toy. Trust me, it is addicting to slide this in and out. It has a wonderful tactile feedback.

It doubles as a small locking karabiner. In the closed position, there's enough gap to put through a key ring, or a plastic bag. A nice accidental feature :)

Multiple lock positions. You can extend and lock the no touch tool in several positions. Useful for any pushing/pulling motions you need to perform with the no touch tool.

Added lanyard hole. I wanted to pocket this tool, with a cord to a pants key clip like https://www.thingiverse.com/thing:6728937.

Components to print:

• raise_base.stl: This is a modified version of mishkin's knife casing that is thicker to accommodate the thickness needed for the no-touch door-opener hook.
• raise_trigger.stl: Thicker version of mishkin's knife sliding mechanism trigger.
• Spring_update.stl: As-is from mishkin's knife sliding mechanism.
• dos.stl: Short for "door opener slider". It's the no-touch hook.

Extras:

• dos.py. This is a PythonScad for modifying the raised_slider.stl to become a door opener hook.

I did not include other PythonScad files such as the one I used to produce the raise_* files. Let me know in the comments if folks are interested in those files.
