Coronatector - Supportless sturdy multifunction door opener and common surface buffer - alternative savegrabber
Description
License, all files: **CC-BY-NC-SA** Although this is not originally inspired from other savegrabbers (late posting), this handle offers similar functions, and a bit more, to allow its user to manipulate a few common surfaces objects without touching them with their hands. **Features**: - Enclosed hand area to avoid accidental contact with contaminated surfaces by design - Rotating door handle opener hook (main hook) - **Both** push and pull - Door lock rotation slot (tip) - *size untested* - Door pin entry pad / digicode pin entry rod at the bottom - Large loop to store it with the contaminated side down - A simple belt hook model is also provided **Characteristics** - Highly sturdy construction allows to pull heavy doors and turn hard handles - Pull and push hooks allow to open and close doors that necessitate simultaneous pushing or pulling force while rotating **Possible improvements** - Full hand shield - Cleaning agent distribution design avoiding possible contamination of the hand handle area If you need another license, I may consider it under certain conditions. **Printing notes** **Walls and other shell parameters** Print with a large amount of walls (>=5) and top/bottom layers (>=4) if the handles you encounter are hard to turn. This is the case for me and worked well with a no-name PLA. **Layer adhesion** Print at a high enough temperature and with the thickness allowing you to get good layer adhesion without any X/Y gaps either. With the profiles I have for my ender 3, this printed well for me @ 210dC and 0.2mm layers, as my current 0.32mm profile has subpar layer adhesion+gaps. The biggest mechanical challenge of this tool will be torsion when opening handles, followed by pulling heavy doors with the hook. **Maintenance notes** Clean regularly with a product appropriate for your plastic, that destroys bacteria and viruses, external side pointing down / internal side pointing up to avoid contamination. I would try to avoid cleaning gels to prevent residues from forming. If an alcohol is compatible with your plastic, and in the limit that I am not a physician, I would advise using a mixture in the proportions advised by the WHO but without glycerol, that only has a hand moisturizing function. https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf Keep in mind that pure alcohol is actually less efficient than diluted at destroying pathogens.
