You need
2 x square nuts
2 x M3 x 16 screws
6 x Neodym Magnet 8 x 4 mm (take the 8 x 4 File)
or
6 x Neodym Magnet 8 x 3 mm (take the 8 x 3 File)
Small file
Super glue
Infill: 20%
Perimeters: 3-4
PETG or PLA
Setting: 0.20 mm Quality
Print the handle upright so no supports are necessary.
Place the magnets into all 8 mm holes. You will probably need some superglue for the magnets on the inside mounts. Do not forget to pay attention to the polarity. The magnets for the inside mount and those of the arms of the handle must be installed with + and - facing each other.
Insert the two square nuts. But watch out! There is no stop, so if you push them too far, you won't be able to get them back. Use a small allen key to pull the square nuts in for final positioning.
Now slide the thumb piece over one side of the handle. This is probably difficult to do. The reason is that the top side is very rough inside due to our position on the print bed. Take a small file and smoothen the insides until the thumb piece can be pushed well over both sides, but still sits a little tighter. If too much force is needed, don't push harder. File again instead.
Alternatively print upright with rim, in order to avoid filing.
Use superglue to get both handle pieces together. Make sure that they are as close together as possible and that everything is aligned.
Once the two parts are firmly connected, slide the thumb piece to the center and fix its position with a small grub screw on the bottom, if necessary.
Now all is left to do is to attach the handle to the window and connect it with the two counterparts on the inside.
This handle only works with steel. If you have an enclosure made of aluminum, the magnets won't stick.
If so you can try to solve the problem with two more magnets, which you position on the inside and fix them with superglue. I have not tested whether the strength of the magnets will be sufficient.
This handle may also work with other enclosures. However, you probably have to drill (new) holes.
If you are looking for my solution for the side doors too, you'll find them here:
