thingiverse

I tried the standard part http://www.thingiverse.com/thing:32622 and the alternative option https://www.thingiverse.com/thing:28788 but they both did not fit snugly on my profile, resulting in a few broken components after 3D printing. Determined to solve the problem, I took the initiative to design a new part using SketchUp. Files for download include: STL and SketchUp formats available in two options: x1 - A single part x16 - 16 identical parts Dimensions of this component measure 15mm by 12mm by 3.5mm, with a hole suitable for a 7mm nut at a diameter of 7.2mm. I utilize the following profiles to get an optimal fit: For 20x20 profile, I recommend visiting http://www.alu-profil-technik.de/product_info.php/info/p14_aluprofil-20-x-20-nut-6.html And for the 40x40 profile, please see http://www.alu-profil-technik.de/product_info.php/info/p341_aluprofil-20-x-40-nut-6.html Tips and Guidelines To print these components effectively: Print using PLA material Use a nozzle diameter of 0.4mm Optimize layer height to 0.2mm It's remarkable how printing four pieces took less than 13 minutes.
