RAINBOW ROLLER-COASTER - KINETIC CIRCLE SCULPTURE

3D model description

Light up your bleak autumn days with this kinetic sculpture. RAINBOW ROLLER-COASTER is an addiction making matter. You will not be able to tear your eyes off! Smooth movement is ensured by one motor and the whole assembly is very easy!

You will need to print:

Circle A - 1x
Circle B - 1x
Start gears - 2x
Blade gear - half - 42x (so get 21 Blade gears after gluing)
Mechanics - 1x (use supports)
Blade - 42x
Stand cover - 1x
Stand - 1x (use supports)

Assembly instructions:
1) Glue the two circles together.
2) Prepare the gears, glue them together by the flat sides. Make sure, the slots for the blades are matching.
3) Slide the gears onto the circles one by one. You will have to incline them a bit.
4) When clustering the gears, make sure every next one is rotated by one teeth.
5) Last two gears are the start gears. The big circle is ready for now.
6) Take the Stand and slide in the mechanism, it is a series of gears and shaft. Slide in the Stepper motor and place the motor gear on the shaft.
7) Carefully slide the big Circle with the gears into the Stand (to the top rails) You do not have to go fully in. The gears must move freely. So once the gear from the stand connects the gears from the Circle, stop sliding in.
8) Place the stand onto the Stand cover.
9) Now you are ready to install the Color Blades. Perhaps you will have to secure them with the glue.
10) Plug the stepper motors into the x-motor plug on Einsy Rambo, connect it to the PSU and flash the Rambo with eclosed code.

Hi How are you,
Congratulations. Like your design creations. Request if you can mail me video of "RAINBOW ROLLER-COASTER - KINETIC CIRCLE SCULPTURE". Regards

Hi, are there instructions included on how to assemble the entire unit and electronics BOM, code, etc?

This is pretty much like the 2016 Brazil summer olympics display. Good job! I also duplicated it right after the Olympics, using Rhino software.

Hi, my compliment for this project! I was second to buy, and i start print last week, now i start try configure motor with Arduino. I like idea to create with different speed different visual effect. I think a good gift for Christmas, maybe gift for me :)
PS its possible download file with manual upgrade whitout buy again in, My Account-My Orders

@THEMINORS
I assumed it would be available for the people who had already downloaded it as well. I had no idea. Of course, you do not need to pay. Give me your email, or ping me on iam@dominikcisar.cz ;)

@HAIRYFIL
Potentially yes. Or you can cut it into smaller parts in your 3D program or a slicing program, and then glue the parts together.

Will I need to pay again to get the manual-power gearings?

Thanks for the info on size. The Circle and Stand cover aren't part of the mechanism though??? I could potentially build those out of other, non printed parts??

cheers
Phil

@HAIRYFIL
Hi Phil, the two largest objects are the Circle (cca 170 x 170 x 10mm) and the Stand cover (cca 180 x 100 x 125 mm). The rest can be split into single smaller parts. However, your printer is having a smaller Build Volume I am afraid.

What size of build platform is required to print this?
I'm using an Anycubic Photon and unsure if it is large enough to accommodate this model

thanks
Phil

@STEFCAMERA
Hi, that would be awesome, thank you! Or have you considered placing them here online? You can contact me at iam@dominikcisar.cz
Thank you...

I liked your work but the gear is not perfect. so I was inspired by your sculture to make one with real gears.
if you want the models I want to give them to you.

@THEMINORS
Hi, exactly. I do have a RamboBoard and 12V PSU. However, I am working on a modification. I am adding a handle for a manual power;)

Can I assume the stepper motor has to be powered by some sort of board and driver? How did you control yours?

@WOODY3D974
Hi, the printing time depends on your layer height, speed, infill, perimetres..etc. Here is estimate time for 0.2mm, 10%, 2 perimeters:
Circle A - 1x -> 3h
Circle B - 1x -> 3h
Start gears - 2x -> 2h
Blade gear - half - 42x (so get 21 Blade gears after gluing) -> 25h
Mechanics - 1x (use supports) -> 3h
Blade - 42x -> 12h
Stand cover - 1x -> 7h

Stand - 1x (use supports) ->5h
Total: 60 hours

@BLOWFISH2003
I used Electrical Stepper Motor NEMA17 40Ncm. Dimensions 42,3×42,3×40 mm. I had to cut a little bit of the shaft offf.

Hi,
that's beautiful !! Could you tell us how much time to print everything ?

Thanks a lot. Thats really helpful. Can you also please tell the specs of the stepper motor used?

@BLOWFISH2003
Hi, thank you. I have added more pictures focusing on the back and the assembly. It is better for comprehensibility now? Ask me for help, if needed;)

Hi,

Simply amazing design. Is it possible to put the assembly diagram in a higher resolution. Thank you in advance.

I've been watching this creation for an hour 🌪! Thanks, man, that's great job again !
