CTC Prusa i3 Clone Frame Brace 8MM version Geeetech i3 Pro B Pro C, etc..

thingiverse

Originally designed by CTcartesian3D. I have increased the frame slot to accommodate a printer using an 8MM frame: the Geeetech i3 Pro B and Pro C. I have used this brace for over a year now and it has greatly helped stiffen the frame on my printer, allowing faster speeds. You will need to remove 2 bolts holding the Z stepper mounts to the frame. Required hardware includes: 2x 20mm M3 bolts 4x 25mm M3 bolts 4x 30mm M3 bolts 10x M3 nuts 20x 3mm washers Some foam is needed to pad the area between the threaded rods and the brace. You can use 10x 30mm bolts to consolidate fixings without worrying about fouling the print or other parts. Alternatively, you could acetone weld the halves together if using PLA; this may add strength but I haven't tried it or found a need. Any questions, feedback, and comments are welcome. Thanks.
