Walnut machine

    Hi Guys,

    I just wanted to show you a fun project I did with Alibre recently. The job was to design a machine that spews out one walnut per day. So I designed a walnut dispensing mechanism and added a one day timer to the drive.

    The glass was home to some pickles before and I had to guess the thread pitch.

    The bottom is made from walnut wood (I had this turned by a pro - this is beyond my capabilities). Turned out beautifully!

    Knob is 1.4305 and if you look closely you see that I set the facing tool a small bit too low on the lathe.

    Now here's the feed mechanism:


    A small DC gear motor drives two counter-rotating foam squares. Gears are made using the Alibre gear generator (@Alibre: Thanks!!!) and printed from PLA. The timer PCBA was designed using KiCad, which (being free software) absolutely amazed me.

    As you might imagine, quite a few hours of Alibre time went into this:



    Printed on my Prusa MK3S in PLA.

    Regards, Martin

    That is very impressive Martin. The finished product looks terrific!

    Super impressive. Very clean design and also visually. Tidy use of 3D printing and of 3D design tool.

    I presume that the walnut is to feed some critter. Do let us know if said critter eventually comes to be seen to be "hanging about" at around the "drop time".
