    HomeMade/Do-it-Yourself 3d Printer made mostly of wood and hot glue (Under Construction)

    As i have never seen a 3d printer personally in front of me this is really amazing ,I have never made something like this So, this is a great learning experience for me.

    Wood was not purchased and I used whatever I can find and there are 4 different types used.

    The white metal parts are Phillips fluorescent tube light fixtures
    I used a hand saw to cut them.

    Electronics,Extruder,Bearings,Threaded Rods,Belts,Pulleys,Endstops are new Motors and Rods are used .

    Overall I tried many things and remade several things to get this thing which you can see and which might just work long enough to print some upgrades.

    Just looking at the parts move is fun.

    The only thing which is different than the usual printers is that the Z-Axis has it's 2-Threaded Rods Connected via a Closed Loop Timing Belt and this is the largest one available and it also limits the width (X-Axis) of the printer.

    In the Video one motor is turning the Whole thing including the motor on the other side .

    Creating tension on the belt was a nightmare as i had to adjust the whole width multiple times So, that the threaded rods have enough distance to produce tension on the closed loop belt and the difference in the distances of the top and bottom part of the Rods becomes minute.

    Now,I want to use a pulley in the Y-axis direction to pull the belt sideways to create tension.

    The Y-Axis part is made using Linear Rails "extracted" from a Rarely used drawer, hopefully nobody will notice.

    I have a Pcb heat-bed part but I have decided to not use it at the moment and first try printing on glass surface covered with glue and after seeing some videos i'm optimistic about it.

    There is also an issue with the Ramps 1.4 board with its current handling capability so, whenever I will decide to install a heat-bed I will use external mosfets.
