BMW M logo cards and pen holders with nfc tag gap

I designed this card holder for my brother who is a BMW car seller, he wanted a cool holder for his business cards to decorate his desk

I added a gap to insert a pen or any cylindrical item

I added another gap on the back of the model to insert an nfc tag ( round 25 mm diameter, 1 mm thick ) so I could record in it his contact information so the customers can scan it to get it into their phone contacts

A nfc logo is attached on the back, over the nfc tag gap, to show where must be placed the phone to scan the tag

All the parts can be printed upwards without support

You may need to add a bit of support in the M for the nfc tag gap. It depens on your printer

The nfc lid must be glued afer the nfc is inserted so the gap keeps hidden

2 Middle bands stl must be printed to get the full item

All parts must be glued toghether
