Thread Holder Box

Created a box to hold oboe thread spools for my daughter.

Should work with other similar thread spools.

Holds 6 spools with a diameter of  ~36 mm and 12 spools with a diameter of ~25 mm.

Distance from interior box bottom to top is 52 mm.

I have included two separate bottom trays. One tray has longer spool posts and the second tray has shorter spool posts. I had to redesign with longer posts due to smaller spools falling off the posts while the box was closed if the box was turned upside down. 

I decided to include both bottom trays since I already had designed them both. You only need to print one bottom tray.

I also included a post extension that you can print if you decide to print the bottom with shorter posts then feel the need to extend the height of the shorter posts for whatever reason.
