Picked up at a card shop for $5, good deal? #/50 game used Marvin Harrison patch.

Modeled in CAD and 3D-fabricated in my home workshop, this bespoke Derek Jeter Hall of Fame Tribute booklet combines traditional collecting and modern tech. Crafted from iron-gray metallic PLA, the four-leaf booklet houses two full-sized inset custom cards. Inside, is a "color-blast" variant capturing Jeter’s iconic batting stance, alongside a second card honoring his legendary infield leadership. The front cover displays a reimagined Baseball Hall of Fame logo, personalized with The Captain's name and iconic number. On the back, a custom graphic of Jeter in uniform hints at a modern tech feature: instructing the collector to "Tap." Interwoven within this piece is an NFC transmitter — tap any modern smartphone against the back cover, and Jeter’s Hall of Fame induction speech plays on your screen.

This is an exclusive collectible that highlights the professional work of Jane Goodall. This collectible contains 4 multi-layered chromaphane cards in a single-hinged booklet.

At the top is an integrated 1.83-inch LCD screen that powers a 15-minute deep-dive video of Goodall’s life and accomplishments. The video/audio plays using a fully custom Python playback engine coded in my workshop. There is standalone hardware independence which ensures the multimedia plays in any environment. No internet or Bluetooth connection is required.

Every stage of this build – 1) CAD modeling, 2) artistic design, 3) Python coding, 4) electrical assembly, 5) thermal management, and 6) 3D fabrication – is performed in my home workshop.

This piece represents a complete end-to-end creation: no outsourcing or contract work was used.
