Help re-creating adapted utensil for a quadriplegic [R]

I am a quadriplegic with no finger function. My therapist gave me this fork that another OT made before he retired. I am able to wrap my hand around the handle and wedge my thumb underneath the fork as shown, and it has greatly increased my independence. I want to make another fork and spoon version, however I am unable to get in touch with the guy who made this. It's made of some sort of plastic that is dishwasher safe. Any tips on the material and how to make this again is greatly appreciated!

Also would love to hear any ideas about how to make this design universal, so it can be removed and re-attached to different utensils.

Agreed with other posters; the plastic material is overwhelmingly likely to be HDPE. Maaaaybe nylon, but probably HDPE (given its semi-translucent appearance). HDPE is food and medicine safe, dishwasher safe, tough as nails, and easy to work with.

If you're thinking of sourcing materials locally, look for a store like TAP Plastics (this is my local plastic retailer on the west coast of the US). You could also order the stuff and have it shipped; here's a 2ft length of 1" HDPE rod on Amazon for $17.00, which would give you plenty of material to make lots of utensils.

That screw on the top is a stainless, pan head hex (or socket) cap screw, which is a nice fastener but not exactly the right thread for the material (HDPE can hold threads, but the thread type on this metal screw could easily strip it out... I know I sound fussy about the fastener specs, but it matters in this case, since you want to avoid having the screw loosen itself all the time). A better fastener would be one intended for plastic; you want thread rolling screws to get the right anchoring in the plastic. You can find a 50-pack of 1",stainless steel pan head thread rolling screws for $6.44 (again, on Amazon). You'd drill a pilot hole in the HDPE bar that's smaller than the screws' thread diameter, and the screws will self-tap and get good "purchase" in the plastic.

For the thumb detent/brace, this again is HDPE sheet that's been formed into that specific curve. The nice thing about HDPE is that it can be formed using a modest amount of heat; boiling water is all that's needed in order to get it malleable enough to easily shape it into the right profile. That looks like 1/4" to me. You can get HDPE sheet and cut it into strips using a plastic cutter ($5 on Amazon), then cut strips to length, form the strips to the right ergonomic shape, drill, and assemble. Here's a 1/4" thick, 12x12" sheet for $8.50.

Finally, to deburr and smooth the cut lines on the plastic, you can hit it with a propane or butane torch, with quick passes that'll melt the small burrs and help the other marks to level-out.

Another thing to note: this utensil adapter is precisely the type of use case where 3D printers shine, and I'm looking at my 3D printer and the quick 3D model of this I just built in CAD, and I know I can bang these off and ship them to you in no time. I hesitate, though, in recommending only 3D printed parts. I have hundreds of functional prints around the house/garage/cars etc, and I love making functional prints, but as good as I get at design, and the better the hardware gets, functional prints from desktop printers still have strength and durability limitations; extruded rod and sheet are just stronger.
