NFC Case with magnet - Tonie Base - Parameterized

I have designed a simple case for NFC tags. The plan was to make clones of my children's Tonies, as the originals take up too much space when travelling. A magnet can be placed in the centre so that the tags stick to the Toniebox (and other tags).

The model is designed for 10x3mm magnets and the inner diameter is 39mm. If this does not suit you: I have attached a parameterised Fusion file, where all relevant dimensions (incl. tolerance) can be freely set. You can now edit the dimensions directly in makerworld, just click on customize. However, you should bear in mind that the NFC tags need a certain distance (at least 4mm) from the Toniebox in order to be recognised reliably.

Recommendations:

• Use PETG. PLA could be too brittle.
• I used Overture PETG Clear for the lid.
• Model is designed for 0.2 mm layer height
• Magnets 10x3mm
• NFC tags
