So, the Beta Team never sleeps.....
Kataphraktos came up with a great idea to self secure the top cap mini connectors.
One of the more intensive steps in the assembly, is to get glue precisely around the mini-connectors in the the top cap internal with out making a mess. There is not a lot of room and this can be challenging. Kata came up with a simplified approach that can eliminate the glue. Basically we go to a compression fit and put a bar down the middle of the inside of the top cap that rests on the inside of the mini-connectors top surface. When the top cap is fully assembled, it would immobilize the mini-connectors. Well it worked! The only new technique is that you need to make sure your solders are a bit more precise in placement. You basically make sure that the solder points are on the top and/or outside of the mini-connector solder pins.
So for the test fit you just put the internal into the top cap after placement of the mini-connector and made sure of two things. The first is that at the 510 hole you can see the internal is flush against the top cap and has no wobble and the second is that while holding the caps tight together, you cant push the mini connect in from the out side. You can shave the bar down slightly if your solders aren't quite in the right place. If you like glue, you can still use glue as well.
Good news is that its already in the Updated v4.2
So if you recently got prints, you have the new feature.
Here is a picture from Drunk_J showing great solder placement and technique and the new securement bar in the top cap. (We are calling it the "D" Leg)
