Great for school, work, or any other situation where you need to wield a pencil in style. This pencil case holds 1-2 pens or pencils and can be customized (within fusion 360) to be the exact right size for the pencils you want to hold. I wanted to have a new pencil case for school and this is what I came up with. It stores a Hi-Polymer Block Eraser (the smaller black ones) as well as pencils. The magnets (10mm x 3mm, can be changed in fusion 360) have opposite polarities on opposite sides so the case can't be closed backwards and the two pieces of the case will stack when the case is opened. This could be 3d-printed as well.
This is my first real project with CNC milling besides work-holding and test piece and begins my adventure in milling useful items. The work was done on a Shapeoko 3.
CNC - Stock, Cutters, Feeds and speeds
This was milled out of 2, 3/4in thick pieces of poplar.
All of the milling was done using Carbide3D's #201 3 flute 1/4in flat end mill.
Feeds and Speeds
30-45 ipm depending on the cut
0.15" maximum DOC
40% - 100% radial engagement
The holes in the case are just a little bit too deep for that magnets. This means that the force of that magnets is not too strong and the case is easier to open but, it is also convenient for gluing in the magnets. I just put a dab of UV curable glue (epoxy might work too) around the rim of the magnet after I put it into its hole. I also made sure that the magnets on opposite sides will repel one another so the case can't close backwards.
I snapped the box together and used a belt sander to make the edges of each piece flush with one another. For the inside, I just used a piece of hand sand paper.
I put 2 coats of a clear polyurethane onto my case using a piece of 220 grit sand paper in between.
