ANET A8 exoskeleton

thingiverse

It's an understatement to say that Anet A8's acrylic frame is weak... Here is a carbon "exoskeleton" to add incredible stiffness to your printer and reduce z-wooble caused by X-axis shaking the frame. I'm a fan of KISS concept (Keep It Smart and Simple), which means you'll only need one hour of printing to finish the exoskeleton, using very little filament. The stiffness is brought by two pieces of 6mm carbon rods or carbon tubes (find them on eBay or at your local kite shop for less than $10). If you can't get carbon rods, just use metal rods (steel or aluminum) - they'll do the job, but you'll need to add middle junction pieces. I've included a not-so-good video explaining how to assemble it (sorry about the out-of-focus parts) - check it out at https://youtu.be/Jiec6JPh0PI. To make it even stiffer, I added a junction piece where the rod crosses the vertical plate. It's worth noting that these stiffeners don't interfere with the print area; the initial volume of 220x220x240 mm3 is fully preserved. EDIT: You can also download separate STL files for use with 5mm rods in a zip file. I hope you like it - any comments are welcome!
