Hopefully going to have the motivation to create a small series.

I sell the set on my etsy
I use 11/16 in ceramic craft magnets. The links to Amazon die here and there as the suppliers bounce around. I like ones with pole dimples and beveled edges. This link will search Amazon for you :P
This model is dependent on 3 things going right.
The main hole for the magnet should get a very nice grip to the bed surface. However with a Dremel you could scratch away any warping in post.
The bridging for the magnet hole. The hole is about 5mm tall. And I have risen the body to 6.6mm tall giving a nice cushion of 8 layers at .2 to smooth out.
- Finally is the color change at the end of layer 6.6
First off I use Octoprint to run my printer. And have been told this can work with Repetier Host, Pronterface, or Cura
I watch the Gcode viewer until it gets to the very last move on the layer before I change. Overshooting and getting a bit on the next layer is not the end of the world.
I hit the Pause button, and immediately go to controls and drive the head off of the part.
I then retract the current color by 50-75mm in increments of 25 (Be sure to remember exactly how much you retract)
Pull that color out and replace with your new color. Pushing it as far into the extruder as you can by hand (Try as hard as you can to not more the head)
Extrude in the exact same amount as your retracted. Be near by to clean the head as it builds up on the bed.
Pull the extra material away. And hit resume.
It should remember the X, Y, and extruder motor positions and return to that point and begins printing again!
And finally. using the craft magnets mentioned in the main post. I Simply line up the hole with the magnet and press firmly down to snap it into place. If the hole seems a bit too small. I recommend a screwdriver or Dremel to scrape off a bit of extra plastic.
If the hole becomes too wide. I use a strong crafting glue, or some super glue in the hole and press and hold the magnet until they are stuck together.
