Is everything I'd hoped it'd be. Easy to print and assemble, and fun to watch! Can't wait to get all of the kits!

Well designed and prints easily.

Definitely worth it

Extremely fun to create, build and watch! All parts (both in this hardware kit and models printed) are of great quality and fit together perfectly. Thanks again and I can't wait to get more!

I really enjoyed this project! Make sure to dial in your tolerances for the wheels and you'll have no issues. Top-notch design!

Luka has created an amazing package with all of the machines and these jumpstart kits that get things off and running with ease - on top of that he's very active and helpful in Discord which makes everything that much easier to get going.

These have made for hours of fun with my family and we're looking forward to more!

Excellent bit of kit! Printing without supports makes things easy :) Highly recommended

These are all fantastic designs and they work great!

Great you can change the design of the marble Falls

Great Module

Got a nice little beat when the marbles go down the shoot.

I'm really enjoying this design so far. Can't wait to finish printing everything and see it working. Worth the money!

So I ordered my kit and the STL's back on 5/12, the kit arrived yesterday on 6/20...a little longer than expected but with everything going on is completely understandable. The contents of the kit are well thought out and high quality. The exception comes with the completeness of the kit. The batteries were preinstalled into the battery holder even. That was the problem though. Sometime during shipment the leads from the battery tray shorted out on the tray and melted the leads and the tray a little bit. Luckily there were only 2 little AA batteries so it didn't have that much power to cause a fire. Still I feel this is a great kit and highly recommend it, can't wait to finish printing everything and see this thing work!

Printed and deployed to production aka my daughter playground. She is using it right now with a mix o marbles and small spheric bells like the ones you add to a cat collar. Everybody is happy here! We like it!

great

The Hardware package is complete. Nothing else is required. All the items are good to high quality. The files for printing are some of the best I’ve used. The prints are full of details and the pieces fit together very well. You won’t be disappointed with any of these projects. Thank you Luka for sharing your hard work creating this Marble Machine.

Excellent hardware kit! Luka shipped my order within 2 days and it took a little longer (4 weeks as opposed to the usual 10 days here to NZ) to arrive due to the worldwide lockdown but it's now here :) Thanks again Luka, time to print the modules!

Well designed, easy to print, runs like a clock! Thanks

Everything was very easy to print.Love it ! Fast shipping for the E parts

I bought it and print with anycubic i3 mega. It works perfect and looks great.

Both sets of files print very accurately on my Raise3D printers. Well engineered and easy to put together.

Kit was complete, ready to go! Perfect addition to the print files. Highly Recommended!

It's rare to pay for STLs, but this was definitely worth the money.
The design has clearly been refined over time to get to it's mature state with printability in mind.
Not only would I recommend this to any 3D printing enthusiast but I hope this becomes the standard within the 3D printing community.

The engineering and the accuracy of the prints is very impressive.
He also gives you everything you need to build it except the printer and filament. It is running so well, I think it can run all day without a miss-hap.

Love the design. It prints perfectly fine and everything fits at first try. Going for the Two Wheeler next. :)

Works great! Simple module, but fun to send multiple down at once. Easy to print and assemble.

Just printed this module overnight and it turned out great. Now just need to print the rest of the machine.

fun and well designed

Wonderful product; can't wait to get started with printing.

Easy printing and parts assemble perfect.

I had a lot of fun building this. I ordered the hardware kit and digital download and got to work! People love it, I keep it proudly out for everyone to play with. Thanks Luka!

I absolutely love this module, brings a lot of joy to my kid. Keep up the good work!

Fine stl's

Love to watch while enjoying my coffee

I don't have words, it's great, easy to print and I will never get tired of it, because of all interchangeable modules. I looking forward to print out "The double screw" too.

Using the attached tollerance test was great, everything has been snap fitting good and it is so much fun. Can't wait for my printer to finish it.

here's photo and video.
