Description

Boost Me (for free)

adding a boost will allow me to design even more!!!

I present to you my latest invention: a game of two dice with mechanical launch. You will say to me: "what is different from two traditional dice?", well I will answer that this model is more fun and especially much less noisy.

 

Great for RPGs.
Printing profiles will allow you to choose which dice you will need, D4, ,D6, D8, D10, D10 (tens), D12 and D20.
For example, you can place one wheel on the left D8 and the other wheel D20.


Its exclusive mechanism allows the launch of the two wheels at high speed. The gears on the wheels are of different diameters, which allows them to turn at a different speed, and make the results random. The rotation time is around 30 seconds, if you hit the button violently (not too much though!!!).
The wheels will stop when you release the button, and will necessarily stop on a face of the die.
The viewing windows are large and oblique so that each participant around a table can see the result.
You will need a few hardware to assemble this model (every maker have these hardware):
-Two 625ZZ ball bearings (degreased and lubricated beforehand)
-A ballpoint pen spring
-Four M4X20mm screws
-Four M3X12 screws (up to M3X20mm).

-Optional: 12 X10mm nuts for more velocity

 

important points:
-the pinion shaft is nothing more than a piece of filament (don't forget to shave it off with cutting pliers. See the assembly video)
-add a drop of glue between the button and the push finger

-Be careful about the direction of assembly of the pinion and to close the cover properly with the mechanism armed: push button upwards and the pinion at the stop with the push finger:


Here is the assembly video:

I don't understand what's going on, every time I want to screw the base and the lid together the die faces shift. If I remove the screws everything is well aligned

Did you correctly install the left and right wheels? The cover also has a specific orientation for the pinion gear to drive the slider

Have you correctly installed the left and right wheels? Have you correctly installed the cover so that the pinion can drive the slider?

Also ensure the gear is installed correctly (cross-sectional view)

How easy would it be to create swappable dice plates so you can make custom dice? I specifically need to make a dice that has the numbers 2 through 10 on one side and 3 A's and 3 B's on the other side. Any chance I could get the CAD/Fusion files for just the dice plates?

Easy, no, but achievable The mechanism has as many teeth as there are solutions Each wheel must be redesigned for each desired combination For example, I am currently creating D20 wheels I aim to create left and right D6, D8, D10, D12, and D20 wheels which I will offer in future print profiles Your request is for one wheel with eight solutions (2 to 10) and another with two (3A and 3B), if I understand correctly

My solution would need a 9-sided die for one side (2-10 has 9 digits total). The other side could simply be a 6-sided die with three A's and three B's on it. I like your design so keep up the great work!

I can do this for you, but I need a thorough understanding, as I am unfamiliar with this game Have you noticed that I have added print profiles for d4, d6, d8, d10, d12, and d20? Also, both dice are rolled each time the button is pressed

First, what a work of art! not only the design is clever, but the details are amazing, the built in supports in the screw holes that come off without problems after cutting around the base *chef's kiss*. I am trying to make the d20 version work, but the left wheel won't turn or turn much slower than the right, which is always perfect. I think there is a slight asymmetry in the slider that makes the left part of the bracket (shown right in the picture) reaching out less. The picture shows how it is after I tried to correct it (not enough) by shaving off a little material top/right from the bracket. Before the correction the bracket was more vertical. the original "claw" bracket shows the same issue but not as much. It's either that or the left wheel is slightly farther away from the centre, I can't say. It might be a print imperfection because the first two sliders I printed didn't fit properly and I had to shave a little material off to let them move properly, but then I thought my possibly asymmetrical shaving was creating the problem in the first place. I printed a third slide (the one in the picture) alone on the plate, centered and while it fit perfectly the mechanism was still not working properly.

Hello, I can see from the photo that you rounded the ends of the white spring. You shouldn't! On the contrary, the angle should be sharp! Also, did you put the left wheel on the left, and the right wheel on the right?

I didn't round the edges, it's probably wear yes I did pay attention to L/R

Once again ...awesome work! works perfectly fine and the rolls seem to be even more random! https://vm.tiktok.com/ZNeKV4MdF/ But for some reason the M4x20mm screwes seem to be too long, they should be M4x16mm ones. other than that- perfect, thanks a lot!

I miniaturized it and replaced the bearing of the r188 fidget spinner with a smoother one, eliminating the need for oil removal.

I also replaced the nuts with magnets for self-alignment

Great design. I had to replace the M3x12mm screws with M3x8mm screws and the M4x20mm screws with M4x16mm screws and it finally works 4 stars only because I had to reprint the cover (maybe I just screwed too long)

Other Issues:Good Idea, but does not work well. "Numbers" are stoped between correct positions, next rolling is not working, you must help it to "center". Without weight (nuts) does not work anyway. Bearings were tried at firts to replace by printed cylinder d5.1 /D14.9 and 4.95mm. It works the same as with bearings. Pin at base is very soft. must be careful. Base printed twice Like 1st prototype is good but not for everyone.

Hello, I apologize for any inconvenience All my prints (I've made several for friends) work perfectly Did you place the pigeon correctly? When closing the lid, it must be in the correct position
