Do you appreciate my design? Your support would be invaluable! It will enable me to refine the mechanism and develop new iterations.

Inspired by a 1920s design, I have crafted this credit card-sized gadget.

Select the “no bearing” print profile if you lack bearings. For optimal speed, two 625ZZ ball bearings (EA016 Maker's Supply) and a ballpoint pen spring are required for smooth operation (many makers already possess these!).

Bearings must rotate freely; therefore, they should be immersed in a degreasing solution and subsequently lubricated with WD-40.

For the carbon fiber effect, utilize the Fiber Carbon plate (as shown in the images).

Should you require more than six options on the wheels, please inform me, and I will create a bespoke design; for instance, one wheel with eight numbers and the other with twenty.

 

Inspiré d'un modèle des années 1920, j'ai créé ce gadget au format carte de crédit. Vous aurez besoin, pour un bon fonctionnement, de deux roulements à billes de type 625ZZ (EA016 Maker's Supply) (je sais que beaucoup d'entre vous, makers, en possèdent!), et d'un ressort de stylo à bille.

Les roulements à billes doivent tourner sans friction; il faudra donc les faire tremper dans une solution dégraissante, puis les lubrifier avec du WD-40.

Si vous souhaitez obtenir l'effet carbone, vous aurez besoin de la plaque Fiber Carbon (effet visible sur les photos).

Si vous désirez que les roues indiquent plus de six choix, faites-le moi savoir et je concevrai un modèle adapté à vos besoins: par exemple, une roue avec 8 chiffres et l'autre avec 20 chiffres.

Any chance you have a design with three dice? My family plays a game that uses a 3 dice roll, a 2 dice roll and sometimes a 1 die roll.

Do you need to throw the three dices at once?

Yes. The game is hard to explain, but we throw three dice at once, sometimes 2 dice at once and sometimes 1 dice at once.

So we would need three buttons to control three wheels? Or one button to control two wheels and another to control only one?

Great model. If someone wants to use 608 skateboard bearings, you can do the following to make it work.... 1. Scale the original files to 137.30% 2. Add some negative modifier cubes to the slide so that it fits in the grooves of the case better. Just a little bit off. 3. Print a small spacer or wrap some tap around the posts in the bottom case to fit the bearings. 4. Take the top half of the case, duplicate it and cut the the flat side off leaving 4 layers that can be used as a spacer.

I don't have a model. I would need a .STEP file of the original model to make a new one. Since I didn't have that, I just did the steps above.

Enjoy! do not hesitate to degrease the bearings and lubricate with WD40 for greater velocity.

One side does not spin freely for me, the other is ok , but not as fast as your video. Any suggestions ? bearings were de-greased and spin flawlessly without any resistance

Have you tried without the cover? Is there a rubbing noise? If you reverse the bearings, is the problem reversed?

I tried without the cover and it still is not as good, I think it might be that v-shape piece coming in contact with the dice gear

An idea just struck me… Could you have possibly swapped the left and right wheels? They are different (marked L and R)

Excellent print quality and superb design However, due to the size-sorted numbering, it is easy to obtain very high or low numbers once one gets a feel for momentum and timing Unfortunately, my ball bearings were greased, so I had to remove the grease protection, clean the grease, and then oil them with spray oil to ensure smooth rotation

I find the plate version equally appealing due to its compact and handy size This allows for convenient dice games during car journeys

This print is fantastic! I've been using it to play Four Against Darkness and it works perfectly to allow me to take the game with me. Any chance of getting other standard dice count wheels? D4, D8, D10 (both with leading zero and not), D12, D20? That would allow people to have a full set of dice in a nice stackable format. You could probably safely just put numerals on the wheel instead of pips to make the higher numbers easier to read. Thanks for your work on this!

Thank you for these suggestions I was wondering which numbers people needed Indeed, I had considered replacing the dice patterns with simple numbers I also plan to make wheels for D6 to D20, but the mechanism requires a complete redesign

Fantastic! Getting the bearings to spin smoothly wasn't easy, but WD-40 did the trick! Don't close the top cover too tightly to ensure proper rotation!

Yes, it is strongly recommended to degrease the bearings and lubricate them with WD40, but without overdoing it, as the wheels do not have much inertia

Hi... I am a teacher and looking to make something like this for each student to practice math. I love your design; its simple but effective. Is there a way to have numbers 0-5 or 0-6 one the first side and dots 1-6 one the other side? Thank you so much. Oh, and FYI, I am a 3D printer newbie.

Hello, This mechanism only allows for six possibilities on each wheel I am currently working on another project, but it is true that the mechanism can be modified for more possibilities, independently on both wheels Regardless, I can easily provide you with wheels showing the numbers 0 to 5 on the left one and 1 to 6 on the second

Hello again, I was wondering about that and figured six possibilities was the max on each side. If possible I would need numbers 0-5 on the left side and the dots (like dice) 1-6 on the right side. I use this for learning how to count on. Students put the number in their head and count on with the dots. Hopefully, this makes sense. Many thanks!
