I just created this model in the last 2 days, maybe an overkilled design, but when caffeine met CAD, I have to spend my weekend for this one.
The key features of this design are its solid grip and precise push-and-retract mechanism. With only about a 45–60° twist, a magnet can be fully released. Thanks to the well-designed handle, inserting magnets into a model becomes effortless—twist, release, insert—all done smoothly with one hand.
In addition, the model follows a modular design, allowing internal components to be swapped at any time to accommodate magnets of different sizes.
Thickness: technically all thicknesses, didn't find incompatible one yet
STORAGE SOLUTIONS:
Desktop
A desktop stand, at the moment only for Type A pen
IKEA Skadis
the 2 different types of holders installed with 40mm height difference on the board, and make all the pens aligned.

2 boxes for Gridfinity system, each box can put 1 extra polarity nozzle in it. All pens and nozzles are compatible.
Assembly Instruction:
shown with 6mm pen as example, all other sizes have the same steps, but some parts will look different.
1, Spin the red Gear Pusher into the body
2, Insert the black Magazine into the Gear Pusher.
3, Do not push the Magazine all the way to the end, first push it about to half way, do some spins to make the Gear Pusher some where you can see from the window on the side, just like shown in the picture.
4, Now you can push the Magazine to the end, ATTENTION: twist the magazine to find the notch to insert to the end as shown in the picture.
5, Insert the Drive Cap.
6, Spin the Drive Cap all the way down to move the Gear Pusher to the end as shown in the picture.
7, Glue one piece of magnet on the Gear Pusher. CAREFUL: do not put too much glue that could stick the Pusher with Magazine together.
