Locking door magnet holder

This is a replacement for the magnet holder from child safe door catches like these https://www.amazon.co.uk/Trongle-Magnetic-Cupboard-Protector-Cupboards/dp/B09CTG81X5/ref=sr_1_151?dchild=1&keywords=child+safe+door+locks&qid=1631854772&sr=8-151

The original magnet holder had been dropped numerous times and was held together by mostly glue, so I designed a replacement.

Take the cylindrical magnet from the original and insert when the print gets to about 70% done. The printer will close up the cavity inside after this point, leaving the fully enclosed magnet hidden inside.

I used Cura PauseAtHeight plugin, pausing at layer 63 (layer height 0.2).

First attempt broke on being dropped so I adjusted a few settings to increase strength:
- 40% infill
- 3 wall line count
- Grid infill pattern

Should be trivial to print otherwise.

I was worried the magnet might interfere with the print head being so close and reasonably strong but doesn't seem to. If anything this replaceme
