PRINTA - Ikea Kallax compatible 3D Printer

thingiverse

The PRINTA cube is a simple Core-XY 3D printer, which is sufficient for the daily prints. It is a closed cube and need no additional space around it. The size of the printer was chosen, to make it fit perfectly in a Ikea Kallax shelf or any other shelf. This makes it livingroom friendly and “wife-compatible”. The filament and the cable harness are guided from the back in a 90° angle to the Extruder. Therefore, no additional space above the printer is needed. The printer is using plastic linear bearings for the x- and y-axis. This makes it more silent. The x-axis is using 10mm aluminium rods, which are recommended for the plastic bearings and it saves some weight for the extruder gantry. **Printer Specification** Frame: 2020 B-type aluminum profiles Printer size: 330 x 330 x 380 mm Controller Board: BigTreeTech SKR 1.4 Power Supply: Meanwell RSP-320 24V Stepper Drivers: TMC2209 Extruder: Trianglelabs Titan Aero Clone Printing volume: 180(x) x 190(y) x 150(z) mm Total costs: ~500€ **Software / Firmware Configuration** The printer is running Marlin v2 firmware. The BTT SKR 1.4 board has an extra port for an ESP-01 module. I am using an ESP-12 module instead with ESP3D firmware. You can also use ESP-Link as a firmware for the ESP module, especially when using ESP-01. The ESP module is connected via Serial-over-Wifi to a Raspberry Pi2 with Octoprint. The RPi works as an access point for the printers ESP module and creates virtual serial port with *socat* when the printer connects to the Wifi. Therefore, the printer can run standalone with the power cable only.
