Anet A8 Rear Frame Brace

thingiverse

There are several rear frame braces available for the Anet A8 3D printer, but all put stress on the two screws holding the stepper motor firewall, which isn't the best approach in my opinion. The optimal setup would be to brace the stepper motor itself, but I didn't like that idea because the heat from the stepper motor wouldn't dissipate as well. So, I decided to do the next best thing by bracing the firewall that supports the stepper motor. The frame brace is designed so you only need to loosen the two rear nuts on the middle frame support and slide it underneath. Then re-tighten the two nuts. See pictures for more details. Make sure your slicer program is set to 100% scale, and also rotate the object to make it fit on the heat bed. Be sure to use a front brace as well; check out this design at http://www.thingiverse.com/thing:1857991. If you have any problems with the design, please let me know so I can improve it if necessary. Also, post a picture with comments if you've made one. Thanks. Leo Update 24.12.2016: I've added a slot for cables. Update 21.02.2017: I've uploaded V2.0, which solves the problem of different rear frame dimensions. Users who have modified their h-carriage mount can now also use this frame brace. Update 26.04.2017: I've uploaded a lengthened version (+25mm) called "Anet_A8_Frame_Brace_Rear_V2.0-25_Leo_N.stl," which was designed for the project at http://www.thingiverse.com/thing:2251940 (02.08.2017: File has been removed and is now available on the project page). Print Settings: Printer: Anet A8 Rafts: No Supports: No Resolution: 0.2 Infill: 20% Notes: Select a minimum of 0.8mm shell thickness and top/bottom thick layers; I recommend 1.2mm.
