Your Very Own Little Pocket Hug With Fusion 360

In this Instructable I will show you how I make a Little Pocket Hug.

I will be using Fusion 360 for the design and a piece of scrap oak.

I will be using a CNC for forming the heart shape but there are other means to do it, Just takes a lot of sanding etc.

CNC machines are dangerous and I will be wearing the correct PPE for the cutting operation which will include, Eye and ear protection and dust mask, Im also using a laser and will be wearing safety go

Everyone needs a pocket hug so lets get to it!

CNC Machine with 6mm ball end bit.

Piece of timber, preferably hardwood.

Laser

Boiled Linseed oil to finish or lacquer

The process is more or less the same as the first Heart in Oak Instructable I did but I will go through it again as things have changed when importing Mesh files.

As usual we create a new component then create a sketch on the Top plane.

The Heart needs only to be something like 30mm remember its going in a pocket or Purse etc.

So what I do first is create a square of say 80 x 80 mm then extrude it to the depth of the wood, which in this case is 20mm then Finish sketch.

We now create a new sketch using the top face of the extruded component, we then select the centre circle tab and create a circle of 75mm and extrude it -9 we are cutting both sides of the wood and I don't want it to cut all the way through, we only need to do this on one side as well as we are flipping the piece after the first cut.

Importing the Mesh:

You need to have an STL file of a heart already downloaded at this point, theses are available online.

Along the top line in Fusion you will now see Mesh, click on this to open it and look to the left to and hover your mouse over the Tabs, the one we need is Insert Mesh, once that box opens then find your file and import the mesh into Fusion.

It will land in the centre of the Circle, click on the tab to revolve it so its laying flat, then click ok

We now need to turn the Mesh into a solid, to do this we go to the Modify section and select Convert Mesh, this will convert the Mesh into a solid, click ok.

We can now go back into the Solid section of Fusion and click Modify and Scale, I scale up to around 2.2 on this particular heart.

With the Heart scaled up we now need to centre it, just right click on the 2nd body and select Move?copy and with the white square, move the heart to a central position, then move to the forward face and drop the heart until its just below the top of the workpiece, I then go back to the top view and re-align if necessary.

At this stage we would normally split the body of the heart but there is no need if its not protruding through the bottom of the Piece, but if you were to do it you go into Modify, split body and the the body to split is the heart and then click the base of the circle as your cutting tool and click ok, it would create 2 Halves of the Heart and add another body to the component list, you delete the lower body whichever number it is.

The Final thing to do is Combine the Heart within the stock, to do this modify, click on Combine and then click on the stock piece and then the heart, the function will be join and press ok.

Onto the Machining:

In the manufacturing part of Fusion we click New Set up, and this shows a relative size box around our workpiece,

There is a box saying Body, click on this to highlight the body.

Click on the adjacent tab and in the drop down box click on fixed size box and make all the boxes zero so our work piece will be 80 x 80 x 20mm, the set up is complete, press ok.

We can now go to the 3D Adaptive clearing Tab and from the left with the Tabs select bit, in this case its 6mm Ball end, I disable coolant, but no need to really and spindle speeds and Feed rates can be adjusted here also.

Click on the next Tab is geometry, I just Highlight the top and bottom of the circle and move onto the next Tab heights I leave as is, Next is Passes, Optimal load down to 5mm, click on order of depth, the Stepdown is 1.4mm that is ok, stock to leave is 0.5mm and click smoothing, That's it, go through the preview and make sure its ok, It does flag up an exclamation mark on the toolpath but its only because the top of the heart is above the top of the stock, this is fine as we sand it anyway.

Save the File and rename.

Onto the CNC

Using a suitable size piece of oak, I mark 35mm in from the left hand side and 35mm from the top down, Mark this with a cross and flip the stock over, I then Mimic on the other side, drill holes diagonally and secure the stock to the spoil board, centre the cnc on the cross as we are starting in the middle of the heart, this is our zero, this is set the the router is raised, dust shoe fitted and return to zero.

Download the file, once its cut, flip it and same file again, once that is finished, trim the remaining stock off and then using a Dremel, sand until you have a nice shaped heart.

To finish off I lasered the Little Pocket Hug onto each side and then a couple of coats of lacquer and the heart was finished.

Assumptions:

A pretty long Instructable for such a small thing, but worthwhile in the end, once the design is done the CNC operation doesn't take very long.

I have made a few of these and give them to friends etc and they love them, what better when you are feeling a bit under the weather to have a hug close by.

Hope you enjoyed this Instructable and thanks for looki
