BenQ 3d Glasses arms

These are replacement arms for the BenQ 3d glasses that take the batteries (not the rechargeable ones).

The original glasses seem to have a bad design where the arms break really easy. I included two versions.. one with pins like the original you could friction fit or drill a little hole in to use the original screws and another with extra long pins so you could melt the part of the pin sticking through with a soldering iron to keep it in.

Update: added thick version of arms that also don't open wider than 90 degrees. If you print with 90% infill it will help keep the glasses from being so front heavy.

Make sure you have very good supports set for the pin. Depending on your printer setup you may need to scale the part up or down one percent in size if you want a tight fit.
