Truly touchless customizable door opening tool v1.2

thingiverse

This is a customizable, parametric 3D design for a "truly touchless" no-touch tool that lets users open doors, push buttons or pick up objects without touching them with their hands. The tool itself, which could be contaminated by surfaces it touches, is hidden in a sleeve and protected from accidental touches by the user. Usage ====== Use the tool to open doors, push buttons, or pick up objects without touching them with your hands. Extend the tool by pushing the knob with your fingers. Watch a video of the basic functionality here: https://youtu.be/b8Q2DCqatQQ You can lock the tool in its extended state by moving the knob sideways into the diagonal slot. In daily use, you can attach the tool to your pants, belt or pocket using a lanyard or an extensible "badge yo-yo". The end cap has a slot for attaching it. The tool should offer some protection against accidental touch infection through its design. However, users may want to disinfect it. For disinfection, the tool blade can be rinsed in alcohol or any sterilizing liquid, or wiped off with a suitable substance, depending on your context. If you want to be able to sterilize the tool, make sure to print it with a material that can literally take the heat. Common materials like PLA and PETG are not heat-resistant enough. Customization ============= The model is almost totally parametric, so you can change everything - make it taller or wider, change some functionality, use different means of attachment, generate different quality - by changing variables in the SCAD file. In the default configuration, the model generates an STL file with all the parts for a tool that is about 9.5 by 3.5 by 1 cm, held together by M3 bolts. For a more extended overview of common customization use cases see the [master README](https://github.com/phrxmd/touchlesstool/blob/master/README.md) on Github. For a detailed overview of all possible customization options, you can also see the source code, which is documented. You can customize pretty much everything - dimensions and functionality. FAQ === The tool currently cannot be used well with capacitive touchscreens because they react to the electrical conductivity of your finger, and the printed material has different electrical properties. You could try to print it in a conductive material, or integrate some wires into the tip. Older (resistive) touchscreens do work somewhat better.

Licensed under Creative Commons ShareAlike-Attribution 4.0 International. The original idea comes from a non-parametric Fusion 360 design by Elwin Alvarado [published here](https://www.prusaprinters.org/prints/27210-truly-touchless-no-touching-multi-toolhook). Used with permission. This version here was rewritten in OpenSCAD for easier customization and has an extended set of features - notably attachments for a rubber band, tool locking, printable bolts and others. Version history ============== - v0.1: Initial design based on SCAD adaptation of Elwin Alavarado's original idea. Added rubber band fixture v1: vertical slot, ring around bolthole - v0.2: Added bolt to model; rubber band fixture v2: round hooks on front and back (slips too easily) - v0.3: Added lanyard slot to endcap; rubber band fixture v3: hooks on the left and right (too strong) - v0.4: Horizontal locking slot; screw-through bolt design; rubber band fixture v4: open space with rubber band posts - v0.5: Diagonal locking slot for easier printing; added screw hole to endcap - v1.0: First published version - v1.1: Added keyring hole to endcap, based on [this idea](https://www.thingiverse.com/thing:4275480/) from [Matt Bordoni](https://www.thingiverse.com/matador/about); fixed a few bugs - v1.2: Added debugging for parts placement below XY-plane
