This adapter enables you to use a 16mm spring tube, as output from your Dillon case feeder.

It requires you to remove the metal clip - and is handy if you've removed and lost the metal clip. Use a countersunk M3 screw to attach to the case feeder.

If you don't want to remove the metal clip, see the "Dillon Case Feeder to Spring Tube to Lee Tube Adapter" instead.

Depending on your print settings, smoothing the layer lines by sanding the print a little may be a good idea.

I used a custom M16.5 thread for attaching the spring.

Use supports when printing (I use organic tree supports).
