Printing and assembling this device takes less than a day. It costs approximately €4 and works remarkably well. To get started, you'll need: Amazon product B00RK57NUS and Amazon product B00H8UU3R0. If you multiply the cost of the feet by two, you can produce six bearings for around €1.50 each in plastic, plus €2.50 for balls. I recommend testing a single cage print first to ensure that the steel ball stays within the cage and can still roll freely inside. A 0.15mm gap seems to be just right, which is the dimension specified in the files.
