RPG Spinner (D20,D12,D10,D8,D6,D4)





Introduction: RPG Spinner (D20,D12,D10,D8,D6,D4)

I started this little project with little more than a dream of making a silly toy actually do something useful for us nerds. The first version I made had 1-20 on one side and 1-10 on the other. I decided to shoot the moon and get 6 different dice sets of numbers on it when I re-designed it.

Step 1: Designing the Dial

To start with, I designed the dial for each side using Excel tables. (This is also why all of the numbers are facing the same direction) It's a complicated table, but not difficult to work out. From there I took screenshots of each side and made svg files out of them. (There's tutorials and free services out there to help with this)

Step 2: Design in Tinkercad

Once I got a good set of svg files I imported them into tinkercad and used them to make holes in a cog design. The most important thing to do when making a spinner is get the sizing right. Standard 608 bearings (this is what almost all spinners use) require a 22mm hole to be pressed into and the thickness of your design should only be 7mm.

Step 3: Design a Cap

You can either design a cap for your spinner, or do like I did and modify a cap style you like to make yours. I found one that I really liked and modded it to make the custom one you see in my pictures. The original design can be found here (https://www.thingiverse.com/thing:2320555) I highly recommend his design as a starting point for designing quality caps.

Step 4: Get to Printing

Here it is, the final step. Load the files in your slicer and print them out.

    awesome idea has there been any complaints with the spacing of the numbers it seems the higher numbers are focused on one side any great idea

    No complaints with this one. my first one had some complaints cause the numbers weren't randomized. The only thing I don't like is the numbers aren't aligned to the center like I'd like.

    Very cool idea, I love that you've taken the fidget spinner and added a new level of functionality. Solid work! :)

    Did you print in red, then paint the surface gold?

    When I sliced it to print, I preset a pause at 1mm and again at 6mm. When it paused I just changed my filaments.

    Neat! Now I'd like to see if there's a way to do 4dF and/or 2d6 on a single spinner. But that's 81 or 36 outcomes respectively, which could be ugly to fit on a single spinner.

    Yeah, that might be a bit on the difficult side.

    OK - Awesome 'ible, and great build... but.... as a DM, I wouldn't allow it.

    My problem with all of these "Dice" alternatives is that they take the randomness out of dice. This is a spinner plan and simple, like twister or wheel of fortune. And yes, if you start on a number, and spin with the right speed/ force you can get to any other number you want - sorry you can.

    I also have this same gripe with dice towers. One of my buddies recently tried to cheat with one. He'd line his dice up on a little shelf thing, tip it and the dice would fall down the tower, in a predictable way. I was not impressed when I figured that out.

    But I am impressed with this build!

    Thanks. Sounds like you've had a lot more problems with cheating players than I have. Works pretty good with a good bearing in it I was able to get it to spin for about a minute.
