Coronatector - Supportless sturdy multifunction door opener and common surface buffer - alternative savegrabber by QQuark

Last crawled date: 4 years, 2 months ago

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 notesWalls 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.

Keep in mind that pure alcohol is actually less efficient than diluted at destroying pathogens.
