Slotfinity: A Modular Tooling Tray System

Model Overview & Print Notes

Slotfinity is a Gridfinity-compatible tooling tray system designed for organizing precision cutting tools like drills, reamers, taps, dies, endmills, and more . Unlike traditional Gridfinity bins, Slotfinity is meant to utilize the entire drawer space , eliminating the typical radiused corners and clearances for a seamless, efficient layout. It is endlessly adjustable and changeable as you add more tooling—no need to reprint entire organizers when your storage needs evolve. Features: ✅ Modular Slot System – Available in 1/2 U (21mm), 3/4U (31.5mm), 1U (42mm), 1-1/2U (63mm), 2U (84mm), and 3U (126mm) widths to accommodate various tool sizes. ✅ Gridfinity-Compatible – Uses the familiar grid layout while optimizing for full-drawer coverage. ✅ Customizable Dividers – Slots feature 14mm spacing for precise organization. Tips: 🔹 Printer Size: Two profiles are available for each slot width (1/2U, 3/4U, 1U, 1-1/2U, 2U, and 3U): Standard – Includes all possible sizes up to 6 units wide by 5 units deep. These will fit on any Bambu printer (excluding the larger sizes on the A1 Mini). H2 Series – Includes all sizes above 6x5 up to 8x7. These will only fit on the H2 Series printers. 🔹 Divider Options: Three profiles are available: Brimmed Dividers – More reliable prints, but require extra cleanup. Non-Brimmed Dividers – Cleaner prints, but require close monitoring in the first 30 minutes. If a divider fails, skip object can be used to continue printing. Flat Dividers – Without the jog for adding printed text, but makes it harder to read the labels. 🔹 Labeling: A fine-tip white paint pen works great for labeling the dividers, or you can use a laser engraver if available. You can also add printed text to the flat dividers if you choose. 🔹 Fit Adjustment: Filament choice may affect fit—scaling dividers up or down by ~1% may improve results.   Perfect for machinists, makers, and workshop organizers looking for a flexible, space-efficient solution for tool storage!
