Small wire spool

prusaprinters

<p>This is a small wire spool printed in two halves to avoid supports. &nbsp;The two halves are threaded and there is a small hole for inserting the wire to make spooling easier. &nbsp;The outside rim has small slots for holding the other end of the wire to prevent unwinding. &nbsp;The thread tolerances are a bit tight as I didn't want these to be able to vibrate apart bouncing around in a portable kit. &nbsp;You may want to scale up/down the XY slightly or adjust the clearance in the FreeCAD model if you find them too tight. &nbsp;Alternatively, I found that heating the threads slightly for a few seconds with a lighter right before assembly softens the tiny imperfections from the layer lines &nbsp;just enough to alow them to screw together nicely. &nbsp;The FreeCAD file includes a simple spool winder for a cordless drill, however I didn't include the .amf files here because it isn't very good.</p>
