3D Printed moderator (for air rifle)

Decided to see if I could 3D print a moderator for my non-FAC air-rifle because it was raining and I enjoy the CAD work:

It's smaller than a SAK and cost just over £1 to make, took about 6 hours to print in one piece. Because of the plastic I was using to print it with, it looks a little bit like something you'd buy from Ann Summers:

The threads were chased out with a tap and it fitted onto the rifle very easily. Seems pretty effective but not sure whether it's as good as a commercial product. My non-scientific pressure tests did indicate that it would cope with a muzzle blast higher than that of an air rifle but I don't think it would be wise (let alone legal) to attach this onto a firearm, unless you have it listed on your ticket.

The internals look very intricate. It only needed wrapping in Gaffer tape to withstand the pressure. 

They're not that intricate - difficult to show with a static image. Not totally convinced Gaffer tape would do the trick but for a non-FAC air rifle I reckon it would take the pressure

A mod for air is on my list of projects too.

The printer arrived yesterday,  only had time to assemble and run off a couple of tests.  Needs some tweaks before I get into making stuff, and the workshop was chilly which I don't think helped at all.

It doesn't help - I have to start mine warming with a heat gun otherwise it throws an error. Printing in PLA and PETG I get good results but ABS and Nylon - forget it. I have an enclosure now and going to insulate it better
