Ref.: (LML) Monofilament Handgrip Set and Holder
From: Robert Jerskey, Carlsbad, USA
Dear Pieter and colleagues,
I would like to share very good news regarding "loose graded nylon monofilaments", for those based in low resource contexts where they are not easily available or too expensive:
A fine innovative design of a hand held holder for monofilaments, via a link below that includes description, fabrication, and more.
A biomedical engineer who has spent extended time in Pokhara, Nepal, Arjan Knust, has developed and fabricated a Monofilament Handgrip Set and Holder, using a 3D Printer. I had the pleasure of meeting him at the ILC Bali. Conversation included a demonstration of the handgrips with calibrated, mounted monofilaments.
I have found it to be very well designed, the construction is robust, and the handle very user-friendly. It also includes a neat little user-friendly "button" that when activated, glides and then secures, for both unfolding and folding away, the head holding the mounted MF so as to be securely protected.
The sturdy handgrip ensures that the mounted MF and the handle are perpendicular 90 degrees, for use.
Mr Arjan generously extends free online open-access to the design of the holder for those who conducts or wishes to conduct sensory testing with the monofilaments would have the resource reproduce it via an available 3D printer.
Here is a concise profile of Mr Arjan, from "info" at this website.
"Arjan is working as a volunteer biomedical engineer for an NGO hospital in Nepal and is involved in research at the Delft University of Technology. His key interest is research on the development and maintenance of medical devices for limited-resource settings. He holds a Ph.D. and MSc in the field of biomedical engineering at the Delft University of Technology."
