Powder Trickler

<p>I modified the <a href="https://www.thingiverse.com/thing:2846719">Powder Trickler</a> by <a href="https://www.thingiverse.com/nj_v_n/designs">Nick van Noordwyk</a>, to add a cap to the bottom. That made it easy to add some weight for stability. &nbsp;Nick graciously provided his Fusion 360 project file, which made it super-easy to make changes to it.</p><p>The tube does not fit the holes made for it straight off the printer. No surprise there, really. I reamed out the holes by hand with a 27/64" bit, and then the tube fit right in very snug, but would still turn freely. The exact bit to use will depend on your printer.</p><p>After installing the tube, use a marker to mark a spot in the center of the tube inside the hopper. &nbsp;Remove the tube, and drill a hole in that spot. &nbsp;The size/shape of the hole will depend on what powder you're using. You can print multiple tubes for different powders, if necessary. I drilled a 4mm hole, which seems to work well for IMR4895 rifle powder.</p><p>I filled the base of the trickler with #8 bird shot, and attached the bottom cap with hot-melt glue. The extra weight gives the trickler good stability to operate it with one hand.</p><p>&nbsp;</p>
