On the left is the iSlab—a lightweight, customizable slab modeled after the iPhone 16 Pro Max. Printed in aluminum-colored filament with a sleek, smooth finish, it can be tailored to fit any card or card holder.On the right is the team-specific holder, designed for top loaders and one-touch cases. Compact yet versatile, it can be colored and inscribed to highlight a favorite team or player.Both pieces were fully designed in CAD and fabricated with precision using 3D printing technology in my home workshop.

Welcome to the Baseball Card Collecting Mantel Group!This is a community built for collectors who live and breathe baseball cards—from vintage legends to today’s hottest rookies. Whether you’re flipping through ‘50s cardboard, chasing 1/1s, or just cracked open your first blaster box, you’re in the right place. Our goal is to create a fun, welcoming space where collectors at every level can connect, share, and grow. Post your latest pickups, show off your PC, trade tips on grading and storage, or just talk shop about the players and sets you love. You’ll find hobby news, release day hype, market trends, and plenty of chatter around what’s heating up (or cooling off) in the baseball card world. We’ll also keep an eye out for big pulls, unique finds, and maybe drop a giveaway or two along the way. No matter what team you root for or era you collect, this group is for anyone who loves the stories and history these cards capture. Let’s keep it friendly, helpful, and passionate—just like the hobby should be. Thanks for being here—and let’s trade, talk, and collect some cardboard!
