About this 3D model

Summary 06/14/2022 Updated： Upload new version for 3030 profiles. Have a try! Someone said this one might doesn't work, but he tried 4040 25% scaled smaller can fits perfect for 3030. The same day updated: New parts for 2020 aluminum profile. If you find it loose when fixing it into the profile, just scale a little in the slicer software. Sometimes when you want to attach stuff to the aluminum profile, you must disassemble the whole structure. It's really miserable :( Now we have this, just 4 parts can be easily printed without support, just download and follow the diagram pictures and try. You can also use your own parts to replace the "Clip_holder" part. The files uploaded are for "4040" aluminum profile, I will make a new one for "2020" later. Welcome to upload your specific holder parts in remixes. Enjoy! See my other designs at: https://www.thingiverse.com/wuguigui/designs Post-Printing
