I love the AMS Lite Enclosure. It's a great solution. But, I've been having some trouble reliably feeding filament through either of the two grommets in the model. So, I decided to try my hand at making a small improvement. The solution I've come up with is really helping me. I'd love to read some feedback.

I actually like this benchtop drill press. But I've always thought the knobs were cheap. Here's how you can replace them with something stylish and more functional. Spheres provide more leverage, and comfort through the drilling motion. Cutting away the existing rubber-ish cover is easily done with a box cutter. Please be careful. You'll expose an odd shaped M8 nut that can be discarded. The print is all standard. Just tap the shaft into the sphere to reach the threads.
