Black PETG - https://bit.ly/4oWM88M White PETG - https://tinyurl.com/ysyxssuj Pla Matte Navy Blue - https://bit.ly/4oUglVY In this video, we analyze one of the most important, yet most overlooked, topics in 3D printing: how to design holes that actually fit together. It doesn't depend on the printer, the material, or the slicer; it depends on understanding how geometry behaves according to orientation and designing it correctly in the 3D model. Throughout the video, I review the most common situations when working with rods, screws, or shafts, and explain how to achieve consistent tolerances without making ten versions of the same part. Holes in Vertical Walls When printing horizontal holes within a vertical wall, the top portion is often slightly deformed by overhangs. In the video, I compare the standard circular hole, the teardrop-shaped hole, and the hexagonal hole. You'll see that the circular hole is the least precise because the printer tends to close the top portion. The teardrop-shaped hole, on the other hand, eliminates the overhang and maintains the actual diameter much more accurately. And the hexagonal hole, although it requires slightly more tolerance, offers a very strong grip thanks to its contact points. Each has its use depending on whether you're looking for precision or a firm hold. Holes in Horizontal Surfaces (Vertical Rod) When the rod enters from above, we typically rely on friction. In the video, I demonstrate how the circular hole with tolerances works and why its behavior changes with use. Next, we see the variant with a vertical groove, which allows the wall to open slightly and adapt stably to the rod. Finally, the version with two elastic tabs offers the most controlled and uniform grip, ideal for parts that need to hold a rod without play and that will be frequently disassembled. Holes on Floating Surfaces If a hole is located in the middle of a surface with nothing underneath, supports often produce poor results. To avoid this, I demonstrate two very simple techniques: covering the hole with a thin layer of about 0.2 mm, which creates a perfect ceiling and is then removed with a deburring tool, or using two small perpendicular bridges when the hole is small, such as where the head of a screw passes through to the screw itself. Both options allow for printing clean holes without using supports. What you will learn This video teaches you how to choose the right geometry depending on the orientation, understand which tolerances to apply to obtain accurate measurements, how to avoid typical 3D printing distortions, and how to prepare your own parametric tests in Fusion 360 to adapt them to your printer. It's a practical guide for anyone who wants to design functional parts and achieve consistent fit without relying on a slicer.
