HyperCube BlueBeast

Finally finished to work on my first designed 3D printer... As a base, I used a nice design of HyperCube 3D printer by Tech2C. In general- its something between HyperCube and HyperCube Evolution in therms of printed volume size: L300xW200xH250 mm.
Design considerations:
1. Safety: enclosed printer with hidden electrical and heated elements as much as possible, to make it inaccessible to little curious fingers of my children to touch accidentally something that shouldn't be touched
2. Cost effective: using cheap still reliable parts to reduce total cost to fit the budget
3. To maximize building volume with standard parts, with relatively small external dimensions to place the printer during operation on limited-size table, and to storage it while not in use.
4. To avoid two-sided heated bed support like big volume beds (like in HyperCube Evolution)
5. In the end to get simple and reliable 3D printer that easy to use without intense maintenance
6. Aesthetic design

In order to build the printer I have designed 3D model in Autodesk Inventor software. In following link you can find native Inventor assembly, and STEP files for enclosed and a regular version of the printer.

Why I'm referring to another site? Because in GrabCAD site you can view the 3D model in your browser without downloading, and even make measurements- what you can't do here.
Main parameters :
- CoreXY kinematic system
- Printing area 200x300x250mm
- Silicon 220v heater for super fast preheating of printing bed
- Enclosed printer with acrylic 3mm panels
- Enclosed ventilated electronics chamber at the bottom
- LED strips for lighting of the printing area, with switch button
- Based on Arduino Mega with Ramps 1.4
- Frame made of aluminum 20x20mm profiles
- Bowden extruder
- External USB connection for updating firmware
- External dimensions L540xW400xH500 mm
- External Spool Holder Folding

If you want to build a DIY 3D printer by your own, you probable may find some useful solutions from that model - same manner I found inspiration from other creative people :)
Have a nice day :)

P.S. Sorry guys not publishing all STL files for now, don't sure anyone need it (and don't have spare time to spend on it right now...)
