This is a customizable stand made to hold filament spools being used as parts trays. It has been designed to provide you with the shortest possible print time under any conditions.
This is one part of a much larger project. The other parts that go with it can be found below:

This is my first project in OpenSCAD, so if you notice any bugs, issues, or potential additions please leave a comment.
With the right settings there is no limitations to how you print this part.
I have printed it at .3 with a .4mm nozzle and I have printed it at .8 with a 1mm nozzle. You will only have to adjust your settings accordingly.
Some of my suggestions are as follows:
- Wall Thickness - close to an even multiple of your extrusion width, print with enough perimeters to avoid infill.
- Top Spool Tray - 10 or less, this is only there to keep the spool above from sliding down.
- Tray Thickness - 2mm works well for me, you might go thicker if your spools will hold heavy items.
- Spool Gap - This should be a multiple of your layer height. For .3 I use a 3mm gap.
- Race Gap - This will depend on the size of your nozzle and the tolerance that your printer can handle. With a .4 nozzle I do use a .5mm Race Gap.
- Bearing Height - I use 10. You should only change this if your inner spool diameter is exceptionally large or small.
- Center Supports -15 will be plenty unless the inner diameter of your spool is quite large.
- Outside Supports - I suggest 15 or more.
- Support Width - 2 * your extrusion width.
- Horizontal Support Gap - .5mm
- Vertical Support Gap - Use your layer height.
The supports should be easily removed, needle nose pliers or a pick might be helpful in pulling out the center supports.
This was designed through force of will alone. I spent many hours learning OpenSCAD, designing, and redesigning. I am honestly surprised that I was able to include as many features as I was.
