🇬🇧 English: Practical Solution for Structures and Furniture

​Are you missing a cap on a railing, table, or metal shelving? I have designed these finishing end caps for standard steel tubes. They are the perfect solution to protect sharp edges, prevent dirt from entering, and give a clean and professional finish to your welding or industrial furniture projects.

​✨ Model Details:

- ​ Included Sizes: Optimized files for 30x30 mm and 40x30 mm tubes. - ​ Precision Fit: Designed with a slight tolerance for a press fit so they stay securely in place. - ​ Safety: Eliminates the hazard of sharp edges on cut tubes. - ​ Professional Finish: Smooth top surface with rounded edges. ​🛠️ Print Recommendations:

- ​ Material: I recommend PETG or TPU . TPU is ideal because it is flexible and allows for a perfect "rubber-like" fit. If you use PLA , make sure it is for indoor use. - ​ Walls: 3 or 4 perimeters so the insertion tabs are strong. - ​ Infill: 15-20%. - ​ Scaling: If your tube has a very thick wall, you can adjust the scaling by 1-2% in your slicer. ​ DONE! If these caps have saved you a trip to the hardware store, give me a Boost 🚀! It helps me keep uploading useful replacement parts.
