I like to insert 6mm x 3mm magnets in my prints but when the printer is paused they hug too tight to each other; when they're separated, they catapult to all the wrong places. These tools help tame their dramatic tendencies.

• Magnet Sleeve. Take a stack of 6mmx3mm magnets. Insert the bottom magnet in one compartment. Advance the sleeve to separate it from the stack. Repeat three times. Now they're safely stored and individually accessible. Pro tip: use an extra magnet on top to advance the sleeve as you remove each magnet.
• Magnet Placer. Slice the STL file and add a pause at 4.4 mm to insert a magnet in the print. When it's printed use it to maintain consistent orientation with the magnets you're inserting.
• Magnet Guide. If you need to slightly adjust position of a magnet, here's your assistant.
