I made it for Brother bobbins which are 11 mm high and Gütermann threads which are 75 mm high. Height in the container is 88 mm so they are not going to fall off the columns when closed. Brother bobbins are a bit higher as others so if you have smaller ones it will also fit perfectly.
Diameter of the columns is 8.5 mm for the thread and 4.8 mm for the bobbins. There are 19 columns.
Lid is a twist-lock with plenty tolerance.
I printed mine with a 1.4 mm nozzle to be quick and as transparent as possible, the downside is the columns are ugly as heck but I knew they would be. Nothing a small torch cannot fix.
The author marked this model as their own original creation.
