Print in place train STL for a linked toy train with 4 cars and 3 couplings, made for 3D printer owners and train fans who like flexi toys. Nothing is shipped: you download the model and print it on your own printer.

What You Get

• train-print-in-place-print-settings.pdf (1 page)
• Model size: 169 x 44 x 9.0 mm, in millimeters.
• 4 parts and 3 joints (the couplings) that print already linked, no assembly. Each joint is designed to turn 8 degrees.
• Checked in software: watertight, manifold, thinnest wall 1.37 mm and 0.45 mm clearance between the moving parts.

Print Settings

• PLA or PETG, 0.2 mm layers, 3 walls, 15 percent infill, no supports, no brim, 0.4 mm nozzle.
• Bed size needed: 175 x 45 mm or larger.
• Print it in one go: the 4 cars and 3 couplings come off the bed already linked.
• If a coupling feels stiff, bend each one gently a few times to free it.

How It Works

Instant digital download, nothing is posted. Open the STL in any slicer (Cura, PrusaSlicer, Bambu Studio, OrcaSlicer) and print it flat as it comes. Keep the scale at 100 percent or larger.

Licence
