If it fails, what online pencil sharpener do you recommend?



Hi,

I bought a 3D printed replacement gear for my Boston electric pencil
sharpener for around $10 on e-bay. Now there are several vendors, and a
couple of variations, so you could search e-bay for:

"Boston pencil sharpener gear" and find several choices.

Regards,
Tim


It probably will not work but I'll try to glue it just once.
If that fails, I'll junk it for parts.

To replace the gear I first called Newell Office Company under Exacto in
Statesville NC 800-879-4868 but they no longer support the Boston Model 18
Electric Pencil Sharpener 296A so they won't sell a replacement gear.

I assumed it's nylon where it must be a really bad design given that it
breaks a lot in the same spot on the net https://youtu.be/TExVKWyZx20 so if
an expoxy or cyanacrylate doesn't work I probably should choose a more
reliable brand than this crummy Boston brand.

Like you said there are 3D replacements online I could buy.
There's even a "tinkercad" model file

but I don't have a 3D printer to print it

Someone suggest a better brand they like that's better than crummy Boston?
