Worked like a charm
from on 03/02/2020
I had two broken screw holes on my 41CX halfnut, and ordered the repair kit for a more permanent fix. Rather than glue, I used JB Weld Plastic Bonder, a two-part expoxy meant for plastics, and applied a thin coating to the whole mating surface of the repair piece. With a couple of small binder clips to clamp the piece in place, the set was strong enough after a couple of hours to carefully reassemble the calculator (and then handle very carefully for the remainder of the 24-hour cure time). I don't intend to do any drop testing, but the case now feels perfectly solid for everyday use, and much sturdier than my attempt to epoxy the original screw holes back into place.
Good, but needs a little careful preparation.

A nicely designed piece, printed well. On balance, it does the job. I've bought two parts, for two different 41C's of slightly different vintage.

Slight problems, though - when fitted squarely in position according to the instructions, the screw holes are slightly off position on the case. The tie-bar between the two screw blocks is about 0.5mm too long, and the blocks need a little careful sanding to bring them closer in towards the centre line of the case. Doing this positions the holes correctly horizontally, but not vertically. Setting the correct vertical position for the holes (along the line of the case centre line) then leaves the horizontal line of the blocks out-of-place, so a little filing of the outer horizontal edges of the blocks is also required to allow the module contact block to correctly fit into place.

With a little bit of design refinement this item would get 5* from me, but in any case is a clever solution for the repair of the case bottom.

Excellent, recommended - but take your time with preparation before gluing.
Very good

An easy way to fix a broken backhalf of the 41. Easy to follow online-instructions. I´m very glad that this product exists.
