I need a precise 3D model for a custom tool that will be printed on my Bambu Lab P2S in PLA. I already know the overall function; what I need from you is a print-ready design that respects the printer’s build volume, typical PLA tolerances, and Bambu Studio’s slicing quirks (bridging limits, optimal wall thicknesses, preferred layer heights, etc.). Once we confirm the basic concept, I’ll share sketches and key dimensions. I’m happy to iterate, but the final files must arrive fully ready for slicing: • Native CAD file (STEP or Fusion 360) so I can tweak if needed • Clean, manifold STL with correct orientation I’ll sign off when the part slices without errors, shows no red zones in preview, and the dimensions match my spec within ±0.2 mm. If that sounds straightforward, let’s get started.
