Big Model Splitter

The Big Model Splitter cuts a statue, doll or character into pieces that fit your bed, with pins to put it together.

• Big Model Splitter: drop in an STL, 3MF or OBJ, choose how tall it should be, pick your printer, and it is cut into pieces that each fit your bed. Free with a free account.
• Pins that line it up: every cut gets matching holes on both sides and the pins come as their own part to print (with spares), so the pieces go together straight before you glue them.
• Solid or hollow: print it with infill, or as a light hollow shell that saves filament and time. See how many grams it needs, then download STL files or 3MF files with the settings already set.
• In the 3D Designer too: Cut & split → Split for printing now makes clean pieces that slice without repairs, with pin holes and the pins.

Snap-fit hooks and holders, heat-set inserts, ring holders and an arm rack for the Honeycomb Storage Wall.

• In the 3D Designer: Create → Honeycomb Wall makes inserts, hooks, shelves, bins, tool holders and arm racks right next to your own design, ready to join to it.
• Snap-fit: hooks, shelves, bins and holders can now click straight into a wall cell, with no separate insert. Padded adds a flange for a wider face.
• Heat-set inserts (M2 to M5) for screwing your own holders on, and inserts of two, three or four cells bridged together.
• Tool holders with rings of any size, rectangular frames or snap-in clips, and an arm rack for tape rolls, spools and cables. All on the Honeycomb Wall page.

Your photo in a lamp shade — a bell, a dome, a lantern or your own shape — ready for a lamp holder.

• New: Hanging lithophane light (menu: Lithophane → Hanging light). Nine shapes to start from — bell, dome, lantern, tulip, vase, pear, drum, cone, cylinder — and nine diameters to make it your own.
• See it lit: switch the light on in the 3D preview and watch your photo glow through the shade before you print it.
• Ready to hang: a top with a hole for an E27 or E14 lamp holder, a cord, or your own size. It prints mouth down with no supports.
• Beta testers first: while we test it on real printers it is open to beta testers, with no daily limit. Send us a photo of your print and earn Supporter Plus days.
