ToyREP is a tiny and inexpensive FFD 3D printer designed mostly as a technology demonstrator or child's toy. The print volume is 100x100x100mm (125x125x100mm with some upgrades) with a cold bed made of polyacrylate. Hot end is a E3D clone for 1.75 PLA or ABS filament with 0.4mm noozle. Using very cheap 28BYJ-48 stepper motors (with Bi-polar hack) in all axis and geared extruder, Arduino Mega 2560 with Ramps 1.4, DRV8825 and modular RepRap construction based on Mendel, Printerbot, Cherry, Prusa i3 and CARP Box ideas. It is designed to use [12V PSU for LED](http://www.thingiverse.com/thing:947676) lights that should fit under bed. Power consumption is currently ca 40W when heating just hotend and 15W-20W when printing on polycarbonate bed. Or with [100x100mm PCB heatbed](http://www.thingiverse.com/thing:1008121) it will consume 75-85W when preheating and 30-45W in total when printing.
