"I made something like the drinking straw idea several of you suggested.

You push it down over a ball and the ball pushes by the rubber band, but doesn’t come back out. You can keep pushing it over balls to pick up more. You can also see how many balls you have in the loader by looking through the holes in the side.

We’re going to make injection molds for this and have it available on our website, but it will take at least a few months before it’s ready. In the meantime, you can 3D print your own. Here’s everything you need:

Rubber band:

The rubber band is a #31 size (2.5" long, 1/8" width, 1/32" thick). You can find it (or something very similar) in pretty much any pack of assorted rubber bands.

I have two options for you. If you have a 3D printer with a dual extruder, you can print the whole thing in one shot, using PVA for supports, and then you can wash the supports away afterward.

If you have a single extruder (most 3D printers are like this), then you’ll probably need to print it in two sections. Otherwise it would be very difficult to clear out the supports inside the tube once it’s finished printing."

"Here it is in action:"

I printed both halves separately on my Ender 3. I used supports for the rubber band holders - but a nicer printer might not need them. It should be oriented so the holes lay flat on the bed.

Notes:

If you can print using PVA use the single print file. Otherwise print both halves.
