One of the best written Instructables that I've seen. Very clear instructions. Great project for a weaving beginner to get their feet wet at little cost.

I am a 70-year-old having a blast with my new 3d printer. This was a great, simple project to play around with. I didn't have a ping pong ball so I downloaded and printed a moon model from Thingiverse. www.thingiverse.com/thing:3242080 The small model is about the right size and the hole in the bottom fits the spring adapter. The only spring that I had was a little larger than a ballpoint pen spring. I made a quick trip to Tinkercad to design a plug to put on the spring to help it compress better. A great fun project with no frustration. Sort of "Shoot the Moon" instead of a Ping-Pong Popper!

I just received a Silhouette Alta 3d printer and am looking for simple projects to learn with. This one is simple, practical and fun. Thanks for posting.

Kenyer, thanks for the great reply. My comment in no way diminishes your great ible. You are completely correct, use the tools that you have access to and are comfortable with.

As someone who has worn Vibrams for many years this is a great Instructable. There's been a growing generation gap here on Instructables that I have commented on previously. As a 69 year old I look at this and think laser cutter, digital camera and computer and printer to make this, really? Trace around your foot with a marker, transfer to plywood and cut out with a cheap coping saw, follow the mold making instructions. Done. Yes, expensive high tech can do many things but it is often overkill. Creating the mold and making the shoes is impressive. Depending on thousands of dollars worth of equipment to cut out simple wood shapes is not.

Years ago for an apprentice to become a master craftsman a toolbox such as this would be entirely hand cut and fitted together complete with the dovetail joints. The work was judged and it was decided if the apprentice was ready to become a master. I find it interesting that much has changed but remains the same. There is obvious mastery of the software used to design and cut this project as well as the mastery of assembling and finishing the project. Well done!

What amazes me about this is the closeup photo of the teeth that you cut. To get them evenly spaced, shaped the same, and looking like saw teeth that were cut with a Dremel, you must have the steady hands of a surgeon. Great job! Mine would come out as a zig-zag with points.

Thanks for a really great project. I discovered the abacus several months ago and ordered one from China. There are excellent addition and subtraction lessons here: https://www.youtube.com/channel/UCNxgTiv9tRfrN9g4j...If the link doesn't work search for the HEV project on YouTube. These are children's classes explained slowly and clearly, just what my addled old brain needs. What's amazing about the abacus is that you slide the beads and the answer appears. There is no thinking about addition and subtraction, it is a totally different way to think about math.
