Small spool

I found Tamel55's design incredibly impressive, but I encountered significant issues with the inner wall on the male screw when scaling it down to fit my printer's buildplate. The wall proved too thin, which necessitated increasing its thickness by 0.8mm. This adjustment should enable two additional passes using a 0.4mm nozzle - this is the revised file ending in M3. I successfully scaled down the original design to 80% size and printed it without any problems. I also applied similar modifications to the Wile design, increasing the end plate thickness by the same dimensions as the original Tamel55 version. To further accommodate potential future scaling needs, I increased the thickness of _2 slightly more.
