Frequently Asked Questions
🧱 General
Q: What materials are recommended?
A: PLA or PETG — both work well, but PETG is more durable and can handle higher temperatures.
Q: Do I need to use supports?
A: Only the base of the bins requires support. Most parts print cleanly without supports if properly oriented.
Q: What’s the best layer height?
A: 0.2mm provides a great balance between quality and speed.
📶 NFC
Q: Which NFC tags are compatible?
A: Any NTAG215 round tag (25mm diameter) will work.
Q: Can I rewrite the NFC tags later?
A: Yes — tags can be reprogrammed at any time using the Coinfinity mobile app.
Q: Do magnets interfere with NFC?
A: Yes — magnets can interfere with scanning if placed too close. This is why the NFCs are in the side panels. If they were close to the magnets it interferes with the scanning process. See the NFC Setup Guide for tips.
Q: Can magnets erase NFC tags?
A: No. NFC tags use flash memory, not magnetic storage, so they cannot be erased by magnets. However, nearby magnets may disrupt scanning if they’re too close.
Q: Can I customize NFC badges or labels?
A: Absolutely. You can engrave, emboss, or add custom text/logos in your slicer. See the 3D Printing Guide for customization tips.
Q: Does it work with GridFinity?
A: No. The project was inspired by Gridfinity, but our bases are like 6 bases in one, they are a more complex design than the Gridfinity Grid. However, maybe in the future a community member could made a Gridfinity - Coinfinity Base adapter. Or maybe I’ll do it as a stretch goal?
