Comandante c40 grinder half clix (double steps)

As disappointing as Comandante is as a brand when it comes to dealing with its competition, I bought my c40 a while ago and while using it for espresso, I realized that I wanted half steps, even with the red clix (very expensive) mod. This little inexpensive and fast print will allow you to know if the red clix is a worth upgrade for you or, if you already have it, get even more precision. 

I've found this model https://www.thingiverse.com/thing:5370224/files but felt that I was losing precision because the bumps that go into the cavities in the burr were too small. The diameter of those bumps could be increased a tad more and with this current version I don't have anymore the imprecision/slack that I had with the original model. The other modification I made was to increase the diameter of the cavities so that the balls of the red clix don't have to raise too high and dig into the plastic.
