Kossel Delta - gear and belt protector

3D printing is fun! But many objects will fail trying to get the best results. Scraping the debris off the platform results in many fragments. See the first photo, showing the first prototype.
To protect these fragments falling into the space between gear and belt, I designed these simple protectors. An 'U-shaped' block is clamped between the two sheets. The two sheets are hold in place by a strip locking into the 15x15 alumium beam.

Feel free to download, print and use or even improve them.
