Thanx to rkxone for the initial Dominoes set! - https://www.thingiverse.com/rkxone/designs
Dominoes with Inserts
I remixed this just for some fun and because I can't paint, I don't have a multi-color printer, and I thought it looked horrible using a magic marker to mark the dots. This way you can use whatever colors you want and have some fun combinations! These were made figuring on a .2mm layer height for the dominoes and the inserts use whichever layer height multiplies into it - .6 use .2, .64 use .32,.72 use .12, etc. to make it easier to make sure you have the correct size and the slicer or printer doesn't screw up using a 2mm layer height with a .64 height item. Print the dominoes with the open end up, the way it is in the STL.
I printed the 2 pink ones without a brim but then as you can see in the pictures, I printed the entire set in white with a brim. You decide what your printer can do and if you need one or not. I doubt I needed it but I did it just to be safe.
I have included multiple sizes of inserts. Again, it will depend on how your printer does on which one you would need. I use the .6mm one and it fits nice and snug so I use a tiny screwdriver in one of the holes to pop it out a bit to take it out again. If you never want to take them out then put a drop of super glue in one of the dot openeing before sliding the insert in or just a tiny dab at the top before inserting it.
Any questions just give a shout.
Zip file included has all the files and the ReadMe.txt in one place since Thingiverse still hasn't fixed it on their end.
