Magnetic child lock key

For 3 round neodym magnets 19 x 2 mm.
I like the original by lowside, but I wanted something sturdier that won't break that easily and I just had 19x2mm magnets. So I decided to remix it a bit so the magnets can be inside the print.

Insert a pause in the slicer right at the last layer when the hole for the magnets is covered. Make sure you have the orientation you need and then slide them in with a bit of force.

They should slide in fairly easily, but if you need a lot of force just scale the model by 1-3% or something like that and print again. Then resume the print and profit :)
