It is criminal that this is not more popular. The creativity, the printability, the assembly, the functionality... are all phenomenal. Well done. Thanks for sharing with everyone! Printed the marble bearing parts in white PETG Printed the body in white PLA Edit: I forgot to mention, an M2 screw did not fit the motor. I had to use an M2.5 x 10mm to secure the gear to the motor. Maybe the motor's hole size changed?

Thank you for the review and sharing your print, it looks great! And another thank you for pointing out the screw size, you're right it should be a M2.5 screw so I fixed the description 😅

@superhenry

Was your PETG bearings tight? Tried with PETG and could barely spin.

Replying to @superhenry :

I don't recall any issues with it being tight. Also, when it is plugged in and turned on, it doesn't seem like it is struggling to spin or anything

@IONX35

Thank you very much. At last i have a sensible use case for the kit i received with the A1. The model is very well thought out and easy to print and assemble. I printed in JAYO PLA Black and Clear.

You're welcome, making a fun yet functional design was one of my main goals so I'm glad you enjoy it! If you have a second to rate the print profile it helps a lot with visibility.

@user_2704011557

Printing this now! I've already printed the "Upgraded Bearing," and there's a ring that prints around the inner bearing retention ring (smallest ring.) Does that have a purpose? Everything assembled just fine without it, I can't see where it fits into the assembly, and it's not in the video.

(Edited)

The designer has replied

@BrentPeterson

The small ring is a vertical spacer tool to help with assembly; it's not part of the assembled bearing. The plastic balls from the marble run kit are tall enough to self-align with the bearing grooves but with smaller ball bearings the spacer is needed to to align the balls with the grooves.

The table rotates exceptionally smooth. Nice job, well done.

Thank you for your review and for sharing your print, it looks great!

@MJR4PTOR

I am a newbie using bambu lab a1. When printing the center wheel does not rotate and the pieces do not seem to fit well. Any advice to make them fit well?

The designer has replied

@BrentPeterson

Sorry you're having trouble getting the model to fit together. I'm actually working on an improvement to the tabs that hold the bearing since they're a bit prone to snapping if the fit is tight (as you found out). The first thing I'd try is running flow rate calibration on your filament. At the top of Bambu Studio select the "calibration" tab and go through the steps for flow rate calibration (make sure to change build plate). After calibrating flow rate try printing just the bearing pieces and make sure that it is able to spin smoothly like in the assembly video. Once the bearing is working well you can follow the same steps and print the remaining pieces. Let me know if that helps.

@BrentPeterson

@MJR4PTOR I updated the model with a more robust design for the table, try printing the new version and let me know if that works for you.
