Nano Spool

I often purchase small amounts of various color filaments, but it hard to handle well, so I designed a small spool. 2-piece configuration with an outer diameter of 100mm and the inner diameter is 54mm. The thread part is M58, but since it is difficult to assemble, a surface is opened 0.2mm (0.1mm for each thread) using surface offset.
