Box and bobbin for embroidery floss

thingiverse

My embroidery floss was a constant mess so I decided to do something about it that would fit inside the big box I already had. The big box should be 17.7cm long and 4.25cm wide while each bobbin is 4cm by 3.6cm Scale correctly one way and the other should be correct as long as you have them connected. Since it´s so easy to do in the slicer I haven´t had the energy to figure out why it doesn´t scale correctly between blender and the stl file
