Ultimate Omnifixo Pinecil Travel Case

I was inspired by the few Omnifixo Pinecil case designs, but wanted a version that would also hold solder and a brass sponge so I had everything I needed to solder on the go.

This version will require 4x 10mm ball bearings. These ball bearings are the same diameter as the balls at the end of the Omnifixo clamps. So I embed the ball bearings into the printed case and the Omnifixo magnet mounts snap to these bearings nicely to hold everything together. No other magnets are required.

The metal tin I used for the brass sponge is a ½ oz round tin I purchased off of Amazon.com here. It is a 4cm round tin, and I cut off a bit of brass sponge to fit inside. Also, this is the solder that fits perfectly in the case, but you could just bundle up any solder and throw it in that slot.

I printed this with a .4mm nozzle at .2 layer height using carbon fiber PLA (though PETG is probably a better choice). You can print the entire thing then using some force push the ball bearings into the print in the corners. They should kind of snap into place.

Note: if you stick the yellow Omnifixo magnets to the embedded ball bearings with the flat side they will stay stuck to the Omnifixo base plate when it is removed.
