Description

Core - Geometric Planetary Gears Fidget Spinner

This is one of my two new 6 gear planetary fidgets. Circular gears were getting too easy, so here is something ridiculous. Triangles, hexagons and some squiggly lines, yet it is still buttery smooth.

UPDATE due to popular demand I have also released a smaller “Core for Kids” version, which should be more suitable for smaller hands. See sizes below, this page is for the “Standard” version.

See “Core for Kids”: https://makerworld.com/en/models/898296

Also see “Razor” version: https://makerworld.com/en/models/871854

Printed well in PETG-CF. My Grandson will like this a lot. Thanks, you do really nice engineering.

@gmanprojects

nice! i haven't tried PETG let alone CF, it looks really good and happy it works well :)

@weware

Hey, since you mention giving this to your grandson. I don't know how old he is, but just in case - Please watch this video: https://www.youtube.com/watch?v=RLt9l6YxvHk TL;DW: Carbon Fibers can be dangerous

@weware - Thanks, I had actually seen that video and it is a very good point. My Grandson is 26 years old, so probably not any more an issue to him as it is to me, we should all be aware though. Upon re-thinking, since I don't know where it may travel if I give it to him, I will print this in PLA for the gifting. I appreciate your concern and comment.

EDIT: DO NOT EXPORT AS STLs AND THEN IMPORT ALL TO ONE PROJECT UNLESS YOU SEPARATE EACH STL BY PART, WITHIN THE SLICER. (step by step instructions for Bambu Studio located in my reply below). After typing the below text, I went to the slicer to open each project individually. I made an oopsie by exporting each as an stl and importing into one project XD This caused the gears to fuse to the ID and OD of the spinner. Do not be me. **GMAN: It might be worth mentioning this is the text, for those of us who want to print multiple styles at once. If the model is exported from the slicer, itll need to be Separate By Parts once imported to a different 3mf/project/slicer instance.** Hey G-Man! So, I printed Revolver, Core, Pipeline and Blade. Revolver is the only one that printed succesfully. Core, Pipeline, and Blade all fused between the inner and outer rings. I managed to break them free by putting a pair of needlenose in the ID, and opening the pliers to apply pressure, and twisting, but the plastic fractured and made the spinning experience next to ususable. Decided to inspect the gcode path and see that it indeed fuses the inner and outer. Deciding to attempt to fix the issue without scaling, I selected the spinner and clicked "Split to Parts". This eliminated the fusion of the inner and outer rings, allowing it to spin perfectly freely! In the image below, the original from your official print profile, is on the left (edit: this is wrong, since i exported the stls from each project and imported into the project for revolver), fused in the slicer. My "version" Cloned and "separated by parts" on the right. Witholding my reviews until I get all 3 printed via this method.

hi, thank you for the details, yes this is unfortunately an issue in general with models that are close together but supposed to be separate. In older Bambu Studio, i had to explicitly click "split to parts" after importing, but it seems this is default now in order to mitigate this issue. Unfortunately though people still end up with this issue with older versions of Bambu Studio or using something like Ocra Slicer (which i think is based on an older version). I don't know what the correct advice would be, because the advise differs depending on what slicer and what version of that slicer. At least it works correctly for most people, who either print from the Handy app or directly in Studio from the unmodified profile I suppose! I'm not sure if it helps but all these profiles are exactly the same, just different colours assigned for convenience. The mono is just 1 colour deleted in the profile, nothing else.

Replying to @gmanprojects :

I'm on the latest version of Bambu Studio, and the issue was solely the fault of myself. If you right click an object in Bambu Studio, and click "Export as One STL" (picture 1), then go into a different project and "Add Object" and add that exported STL, it imports all parts of the Spinner as one object, thus fusing them together. I'd say, solely since this particular upload is on MakerWorld, to add advice for Bambu Studio. Something along the lines of: If you'd like to print more than one style spinner on the same plate: 1. Here on MakerWorld, click "Open in Bambu Studio" for each style of spinner you want to print. 2. Pick one of the spinner styles to be the plate/3mf file you end up printing. Do nothing with this instance of Bambu Studio for now. 3. On each of the other Bambu Studio plates/spinners, right click the spinner, and click "Export as one STL" (photo 1 below). Save each STL to one location of your choice. 4. On the plate chosen in step 2, click the Add Object button (photo 3 below) and each of the previously exported STLs from step 3. 5. For each imported/added STL file from step 4, you'll need to click each spinner and click the Split to Parts button (picture 2 below). Failure to do so will cause the planetary gears to fuse to the Inner and Outer rings. 6. Print :)

@Megn333

I bet anything this is what happened to my first attempt. Going in for a second one once the current print on my printer is done.

@user_498261825

I’m printing with pla but my first layer didn’t go well, am I suppose to use brim(manually), or is it because I’m using 0.4 nozzle ?

(Edited)

The designer has replied

@gmanprojects

Sorry to hear that, all I can suggest is the generic things - Make sure you give your plate a good wash in warm soapy water, using dish washer liquid is best or avoid anything with moisturizer or oil etc then dry it with a clean towel/cloth. Run the bed levelling before the print, i just always check the box before starting a print.

@user_2945941317

I have similar problems. 4th try and in the 4th or 5th layer the nozzle keeps knocking parts of the plate (Bambu Lab A1, 0,4 mm nozzle, Bambu Lab PLA)

@srpostma11

Replying to @user_2945941317 :

I had this also but if you wash the plate with soad and water and then dry it with a microfiber cloth, it should fix it. You can also do a full calibraiton from the A1 menu on the screen.

@user_2269446374

printed perfect but i can’t get it to spin

The designer has replied

@gmanprojects

sorry about that, is it totally locked up? how did you print it, was it from Bambu Handy, Bambu Studio or another slicer?

@raccoon23

Mine didn't spin either, but I flexed each triangle from the centre until they cracked and now it moves, but sticks/slows at a specific point

Another great design! Printed in Elagoo black and purple pla on an A1 mini. I left a couple of your previous designs at my volunteer gig and was appalled to find some folks, while fascinated by the gears, missed the "put in on your finger and spin" part of the experience. I offer "Demonstrative pointing finger! by mtdna - Thingiverse" as a suggestive display fixture. I'm sure others will design more fit-to-purpose options. WARNING - searching for "finger" will yield a wide variety of selections on a similar, possibly inappropriate theme.

The designer has replied

@gmanprojects

hah that is wild, love the finger model and it is a great idea, i'd probably be a little more immature and go with a middle finger one though.
