Just a little tool to organize sewing thread spools. I made this as my very first thingiverse object for my girl. It measures 210 mm by 152 mm to fit into a box that was lying around. Space for 34 spools leaving enough space for your fingers to grip a spool. Spools up to a diameter of 30 mm should fit without problems (even a little larger if you alter spool diameters on neighbors). Please take a quick look at the instructions.Should print in ABS or very good quality PLA. Bad PLA tends to be brittle and it is easy to tear of the pins. Print it with a shell thickness of at least 0,8 mm. Thicker if you try your luck with PLA or you want more stability. Top thickness do not matter. I printed it WITHOUT the bottom layers, using a nice infill pattern of about 20%. This largely reduces printing time without resulting in a to flexible piece. A last warning: Your printer settings should be nearly perfect in terms of stringing and oozing - otherwise you have some work in cleaning the pins. I printed this thing successfully rather slow on my Prusa i3 with Orbitech ABS in about 6 hours. Most of the time is for the base plate.
