Print all pieces with the flat surfaces on the bed and no supports should be necessary.

It is recommenced that you do use ironing in your slicer and sand off burs on both the arms and the body as smooth surfaces let the fidget flip more fluidly.

The PinCap is the weakest point of the model and it may be beneficial to print spares as they tend to break when dropped. The PinBody has a hole where a toothpick can be used to clear out any debris from the opposite side before a new PinCap is used.

This model is designed to be assembled using friction fits so tolerances may need to be edited if you find parts are not fitting properly.

For the assembly process the arms slot into each other and have room for a pencil to be used to give purchase when getting the pieces flush. (I found the best method with to use a six sided pencil for grip and press the parts down against a solid surface vertically.)

The MiddleBody and MiddleHolder parts are meant to be slid together and this is best done by placing both on a flat surface and pressing them together until they are relatively flush.

The plates of the MainLower, MainUpper and combined MiddleBody and MiddleHolder should then be stacked with the nubs facing the outside and an assembled ArmLower and ArmUpper can then be fitted over the holes before sliding a pin body through the entire assembly.

Then flip the whole stack over and press a PinCap into the PinBody until there is little give but the body and arm can still swing freely then repeat the pinning process with the other arm.

You can now slot a piece of gum into the fidget and have fun flipping it.
