3D-Printed NFC Keychain Tutorial: PNG Prep, MakerWorld Build, Pause to Insert Chip

Learn how to design and 3D print NFC keychains/poker-chip tags from scratch. I’ll show the full workflow: prepping a transparent PNG in Photoshop, converting it in MakerWorld → MakerLab (Image to Keychain), setting plate/thickness and attachments, exporting STL/3MF, and finishing in Bambu Studio—including the negative part cylinder to create a pocket and a print pause to drop in the NFC chip. I also cover sizing (39–45 mm “poker chip”), why simple one-color logos work best, hole placement for key rings, and common failure points. What you’ll learn PNG transparency workflow (vs JPEG) MakerLab: circle shape, background on/off, multi-color mapping, plate & thickness Practical dimensions: 3.0 mm base + 0.5 mm logo = ~3.5 mm chip thickness Bambu Studio: split parts, Add Negative Part → Cylinder, center/move to correct Z, slice preview check Pause at layer to insert the NFC tag, resume without errors Avoiding tiny/intricate details with a 0.4 mm nozzle Chapters 00:00 Intro & examples 00:38 Transparent PNG in Photoshop (Select Subject, mask, Export As PNG) 02:20 MakerWorld/MakerLab (Image → Keychain, circle plate, colors) 04:35 Thickness: 3.0 mm base + 0.5 mm logo (≈3.5 mm total) 05:45 Attachments: hole/loop placement, strength tips 07:05 Export 3MF & STL 07:30 Bambu Studio: split parts, negative cylinder pocket 09:10 Set layer Pause to insert NFC chip 10:05 Troubleshooting (errors, overlapping parts, tiny details) 11:10 Wrap-up & next builds Gear/Settings used Bambu Lab A1 (0.4 mm nozzle), PLA NFC coin/tag (fits pocket ~Ø28 mm x 1.5 mm in this demo—adjust to your tag) : https://amzn.to/4pBKhas Photoshop (any editor that exports PNG with transparency will work) Want my plate files and slicer profile?
