A quick fastener designed specifically for 3030 aluminum extrusions allows for hassle-free assembly without disassembling the printer. Simply insert it into the slot and twist 90 degrees to secure items to 3030 extrusions, making it ideal for components like spool holders on top or webcam arms that need easy removal for transportation or other reasons. This versatile design is intended for use in various models, which is why a STEP file has been provided for import into Fusion360 or similar software, enabling users to incorporate this part seamlessly into their designs. Additionally, two test .stl-files featuring support blocks under the "wings" of the screw have been uploaded for reference. After testing with extrusions from three different manufacturers, it appears that this fastener works well across various brands, but if you encounter any issues, please leave a comment and consider uploading a remix that has proven successful in your case!
