Wanhao i3 Cube Frame

thingiverse

This is a front cube frame for the Wanhao Duplicator i3. I uses square cross section aluminium profiles. It includes ideas from the otherwise excellent Z-Braces mod (http://www.thingiverse.com/thing:921948). BOM: 8mm threaded rod 4 8mm nuts 20mm x 20mm Aluminium extrusion profile cut in (+- 1mm): 4 x 154mm bars (horizontal/bottom) 2 x 331mm bars (vertical) 1 x 365mm bar (horizontal/top) 22 M3 nuts (length > 10mm). The original ones are too short (length = 6mm or 8mm). UPDATE 1: modified top_left and top_right plates, to allow more room for the 8mm nut. Added length of bars in summary. Print Settings Printer: Wanhao Duplicator i3 Rafts: No Supports: No Resolution: 2 Infill: 75% Notes: No supports needed. Expect some plates to break when hammering them to the aluminium profile... If you do it gently, you can maybe lower the needed infill. YMMV Post-Printing Step 1: Cut the aluminium extrusion (20mm x 20mm) to length. Mount the tubes with the connecting joints and plates (first bottom then top). Step 2: Screw the bottom left (or right) hand side to the Wanhao frame (see photo). Carefully clamp the original frame!! Repeat with right (or left) hand side. Step 3: Install upper part of the frame. Step 4: Cut the threaded rod to length and screw it to both sides. Use a carpenters square.
