Truly touchless (no touching) multi-tool/hook

Basically all the others "no touching" tools do not have any type of enclosure and/or they fail in the "no touching" requirement, they do help in minimizing the degree of bacteria but they're not totally hands-off.

At this design, I try to solve that dilemma having a full enclosure that ensures the tool/hook won't touch your hands or your clothes once retracted. Being as ergonomic as possible, its dimensions and form are inspired by the normal postures of the human hand.

The main purpose of this multitool is a Door Hook and Button Presser but it also can be used as a Bag Holder. (One tool to rule them all when going for supplies!)

A sex bolt (also known as a barrel bolt, Chicago screw or connector bolt) has to be used as a guide, however, this bolt can be also 3D printed. It can be used for both Right-handed or Left-handed people.

You can put it in your keyholder or add an auto-retractable keyring for easy access.

Four little magnets can be added for an extra force at the closing and thus avoiding accidental wobble or slide out of place (a satisfying click is also felt when you close it due to this).

Once used, can be put in alcohol in order to disinfect it as explained at the guide:

I hope you enjoy it and #Stayhealthy!!!
