Note that one BitBlock slot is 24.375mm so your overall length must be your number of slots multiplied by that, plus what ever additional length you require.The reason why the overall length is configurable separately is so that you can make the rack longer in case the cutout in your foam board is longer. Or you can just use it to round to the next full millimeter.For example, you you want 5 slots your rack length must be at least 121.875mm (5 x 24.375mm) but you can round it up to 125mm.Print SettingsPrint the two halves as shown below.Post-PrintingTake the two halves and glue them together using superglue or whatever glue works best for the material you used. If necessary, you can sand the contact surfaces smooth before gluing.
