This is a pretty amazing piece of engineering, and I have to thank the designer for creating it. Be warned, though... it has well over 100 parts and putting it together is a big project. The assembly manual is 120 pages long, and it requires something like 200 screws.

Can be difficult to print properly, but a great model.

This simple design works surprisingly well.

Cute!

My son has printed hundreds of these for himself and his friends at school.

This actually works. Some others we tried didn't.

Yes, this thing is really long!

Cool design with the gears and all. Nice job!

Nice design. It creates great patterns when you move it around on the table.

Cute toy!

Nice. My son printed one of these and painted it to look like his leopard gecko. My only comment is that it's a bit "fat" for a leopard gecko. We thinned it down using the scale tool in Bambu Studio, but it's still a bit out of proportion.

Five stars for these little handles that turn an ordinary Allen wrench into a screwdriver. Nice job! I would love to see a version with a longer handle. I pretty well have to use these with my fingertips and can't get a full grip on them. I know I can just stretch these long the Z-axis using Bambu Studio, but it elongates the diamond pattern and changes the depth of the channel for the Allen wrench.

Very nice planter. I've printed several "kumiko"-type planters like this.

These are perfect for organizing my Gravitrax pieces. I do find that printing two pieces and using one as a "cover" keeps them in place better. I use a rubber band to keep the two halves together.

Very nice design.

Works as well as commercially-available headbands at a fraction of the cost... and you can choose your own colors! My daughters love them.

Awesome! I love the printed roller bearings. They're ingenious and work surprisingly well.

Well designed model. My daughter really wanted this one.

This model is very impressive. It's absolutely enormous and will make a great RC boat. Here's a picture of the bow of the boat with a coffee mug for scale. It was printed in parts on a P1S printer. The reason that I'm giving four stars instead of five is because: 1. It has no assembly instructions 2. There are no mounting plates/bases for motors, servos, electronics, etc. You'll have to create your own mounting parts after the model is printed. 3. There is no parts list or guide for motors, servos, electronics, etc. The developer of the model says that "standard" parts can be used, but if you're not an experienced RC enthusiast, you have no idea what those might be. Even if you do, it would be helpful to have a parts list with specifications (e.g., a 10mm "standard" shaft can be used, but what length?). I'm basically taking a big risk that I can make this work after I print it.

This is a great game and this model of it is fantastic. We've had lots of fun with it as a family. Great job!
