Connectors & joints

Split parts are only half the job. Connectors help them go back together the way you intended.

Connector placement on a cut face in Multipart3D

When to use it

  • Flat cuts need alignment pegs or magnets
  • You remount a Smart Detach piece onto the body
  • Large props must assemble the same way every time
  • You want a dry-fit before glue

How it works

  1. Split the model with the cut tool that fits your seam.
  2. Open Add Connectors and place pins on the cut face.
  3. Pick a connector type and tune size or tolerance for your printer.
  4. Export both parts and test-fit before final glue if needed.

Options

  • Plug

    A peg baked into one half with a matching socket in the other. Choose circle, square, hex, or triangle cross-sections. Prism is straight; frustum tapers for self-centering on insert.

  • Dowel

    Sockets in both halves plus a separately printed pin. Useful when you want a replaceable alignment pin or a looser fit you can size independently.

  • Snap-fit

    Clicks together and resists pull-out. Styles include annular barb, cantilever hook, dual cantilever, and split arrowhead dart.

  • Pin hole

    A hole straight through both halves for a metal rod, bamboo skewer, bolt, or glued alignment pin.

  • Magnet

    Flat-bottomed disc-magnet pockets in both halves. Good for remountable accessories. Presets cover common sizes such as 6×3, 8×2, and 10×3 mm.

Multipart3D treats assembly as part of the product, not an afterthought. Place connectors on the cut face after a planar or area cut, or after detaching a feature that needs to remount.

Tolerance presets cover FDM and resin (tight, standard, loose), or set custom clearance. Non-circular plugs and dowels resist rotation when that matters for alignment.

Connectors use the same local, private workflow as cuts. No account and no file upload.

Tips

  • Print a short connector tolerance test in your usual filament.
  • Prefer magnets for removable accessories; plugs or dowels for glue alignment.
  • Don’t place connectors through thin shells without checking wall thickness.
