We recommend combining the bodies into a single solid before exporting into an STL. Intersecting faces usually lead to failures since the software doesn’t recognize which areas are inside or outside of the model. Overlapping & Intersecting Triangles / / Overlapping and intersecting triangles may produce areas too small to print.
Solving any issues with your models in the native CAD software tends to have better results. We recommend removing noise shells for cleaner contours. Unwanted meshes and noise shells are typically created in error during an STL export. Multiple Shells / / Typically, it’s ideal for your STL to be made of one shell body for printing. It may be necessary to edit or re-export of the original 3D CAD file. This is sometimes an easy fix within the STL, but that is not always the case. Holes / / Missing triangles from a region prevents a closed mesh. Adding thickness or clearance where needed can sometimes help solve faulty edges. This requires STL repair and we recommend re-modeling the areas where the boundary edges were detected in the native CAD software. Many times, bad edges that are very close to one another may be stitched together to close the mesh. Simple STL editing software will enable you to flip the direction of the normal to correct the issues.īad Edges / / The edge of a triangle is not adjacent to another triangle edge. Because of this, slicing software will be unable to create contours for printing.
If you have questions or missed information, use the comment section below or send me a message.Inverted Normal / / A triangle’s normal is flipped the wrong way which creates an open mesh. I hope you find these boxes useful these well-prepared models will save you some time. Print these parts in the orientation shown in the following images: body lidįor best results, use the following settings: All file names start with the project number, LR2061 followed by the size SSHH where S stands for the approximate inside width and depth and H for the inside height in cm.
Print Instructionsįor each size, there is a pair of STL files. The box in the following images was made on a Prusa i3 MK3s printer, using Prusament PETG Transparent, with 0.2mm layer height with the default slicer profile “0.2mm quality”.
