Muurhaakje is a self-hosted inventory for all of it — filament spools, electronics, screws, board games, seeds. Create a tab for anything, give every item a labelled bin, and let AI fill in the details from a photo.
Three steps. No spreadsheets, no digging through unmarked boxes.
Add a tab for anything you keep — parts, spools, tools, games. Pick an icon and a color, and optionally tell the AI what lives there.
Every item gets a unique QR or DataMatrix label for its bin. Snap a photo and AI fills in the name, category, description and a verified datasheet.
Search, browse the wall map, or scan a bin with your phone to see what's inside and adjust the stock on the spot.
Resistors or wood screws, dice or seed packets — every tab gets labels, scanning, photos, AI identification, minimum-stock alerts with a shopping list, a wall map of your bins, and clean exports.
Each item gets a unique code with a printable QR or DataMatrix label — stick it on the bin or drawer and scan it to pull the item up in a second.
Scan a label or tap an NFC tag with the Android app to see the item, its photo and details, then raise or lower the quantity on the spot.
Photograph what's in your hand and AI names it, categorises it and writes the description — steered by what you said the tab holds.
Download any tab — complete with photos and scannable codes — as a nicely styled Excel sheet, Word document or PDF.
Spools are more than items on a shelf: they have NFC tags, weights that shrink while you print, and a printer that knows both. The filament tab tracks all of it — live.
Track brand, material, color and remaining weight of every spool in your own MariaDB — self-hosted, your data stays yours.
Show a QR code, open it on your phone and tap the spool — NFC data lands straight in your inventory, no app needed.
Reads Prusa's open NFC standard (and OpenSpool JSON tags): material, color, weight and diameter are filled in automatically.
Bambu's encrypted tags can't be read in a browser — the Muurhaakje NFC Android app decodes them on-device and saves them to your account.
Link your printer over the Bambu cloud and watch each loaded spool's remaining weight update by itself while you print.
Drop a sliced 3MF on the planner to see if your spools cover the job, keep a print queue, and log every finished print.
Invite others to your instance — each account has its own tabs, its own items and its own printer link, kept neatly separate on your own server.
Make a tab, label your bins and scan to find things back — while the filament tab keeps itself current straight from your printer.
