Thanks for downloading!
We'd love to hear from you if the print was successful.
anwofibot v2- a simple corexy printer
This is my first self build 3d printer. It uses an corexy belt mechanism for the xy axes. For the z-stage it uses a threaded spindle. The design was done entirely in openscad. The electronics is the standard ramps 1.4 board.3D printer parts and enhancements

Update: In v2 i've redesigned some of the structural parts for better functionality. All parts are printed in PLA at 200 °C with 25 % infill, 0.4 mm nozzle.
Update 2: I've added bot.scad containing most of the printable parts. It will be completed soon.
Update 3: I've added bot.scad containing all of the printable parts in parametric format. Also i've changed the z-stage holder as the old model wasn't rigid enough and had too much bow.
The next step will be dual extrusion, raspberry pi + octopi print server and webcam for even more fun :)
I'm also planning on adding an heating chamber for better printing of ABS and HIPS.
