Suggestions from our customers:

Bob (07/16/2018):

While that method works, to do it successfully and safely requires a good a bit of skill. It also occurs to me that most homes don’t have Dremel toolkits . Yet, it is important to your business that people be able to do this job conveniently and easily. With that in mind, I’d like to suggest the following revisions:

It is easier and safer to cut the chip loose with a hand saw than with a rotary tool. Especially if you have a bench vise to hold the cartridge while you do it (most home shops do). Just about any handsaw would do—even a hacksaw. But a razor saw (link) such as a Xacto X75300 (link) or a Zona 35-500 (link) would work especially well.

To more easily and safely thin and flatten the plastic on the back of the chip, first secure it to the narrow side of a piece of a wooden 2x4 with double-faced tape (contacts-side down), and clamp that in a bench vise. (If you have a vise; else you could secure it to your bench top with another piece of double-faced tape. Or just have someone hold it still on a table for you.)

Wrap a piece of ~150-grit sandpaper around the center section of a wooden paint stirrer. Grasp the stirrer by its two ends (like a spokeshave , link). Using your thumbs to keep the sandpaper from unwrapping, work the sandpaper back-and-forth over the plastic until it is as thin and flat as you want.

A few drops of a solvent (such as paint thinner, lighter fluid, WD-40, or oil) should help to ease the grip of the double-faced tape on the chip. Nail polish remover would work, too, but it might dissolve the plastic.

Also, it ought to be obvious to users that fastening the salvaged chips to the printer slots is a better solution than fastening them to refillable cartridges, since that enables one to use multiple cartridge sets without having to supply chips for every set. But it took me a while to realize this on my own. So, be sure to point that out in your next related video.

Here is an even better solution for thinning & flattening the plastic on the back of the chip: 
Secure the chip, contacts down, to the center of the wide-side of a 1”x2" about 6” long with double-faced tape; 
Tape a sheet of 150 grit sandpaper on a horizontal flat surface, face up; 
Lay two popsicle-stick-like (link) spacers on the sandpaper, parallel to each other and about 4” apart, to act as runners. They should be the same thickness as you want the chips (including their plastic bases) to be when you are finished. If popsicle sticks are too thick, look for pieces of cardboard of the right thickness (perhaps two layers from a cereal box); 
Orient the 1”x2” so that the chip faces the floor and its long axis is perpendicular to the spacers. Set it down straddling the spacers, so that chip base lies between the spacers and contacts the sandpaper. Now, rub it back and forth on the sandpaper until both ends of the 1”x2” ride on both spacers simultaneously. 
Voila! You are done and the chip assembly is exactly the right thickness over its entire surface.

Anybody can do that quickly, safely, and successfully. (Note that the final thickness of the chip assembly can also be controlled by adding layers of tape between it and the 1”x2” or to the undersides of both runners.)
