This is the next evolution of your viral HDx Mini Bin system — stronger, easier to print, more modular, and now available in a larger size designed specifically for real-world usability (not just slicer scaling). This update includes: ① New & Improved Lids A redesigned lid that snaps on and off more smoothly, with better grip and a more forgiving tolerance range. Made to withstand daily use without stressing the bin walls. ② New Rack System (3, 6, & 9 Slot Versions) A new rack design that prints easier, faster, and sturdier than the previous faux-2x4 style racks. Each rack securely indexes the bins while keeping them easy to grab and return. Available in three configurations to match your workspace: 3 Slot Rack 6 Slot Rack 9 Slot Rack Perfect for desktops, garages, craft rooms, or inventory sorting. ③ LARGE HDx Bin & Lid Instead of simple slicer scaling (which increases wall thickness and ruins tolerances), this large version is properly engineered at its new size. Walls remain proportionally correct Lids snap on smoothly Printability stays optimal Designed for 350×350mm build plates Finally — a big HDx bin that feels designed, not hacked.
