I made a 3D-printable replacement cylinder for the HammerShot that fits standard 1/2" PETG!

 

It uses the existing ratchet mechanism and requires no dicking around with the seal. Ranges are 30-60 feet with my ancient Slugs, but better darts will probably fly further. This is a really fun blaster and makes a great sidearm.

 

Because I can't attach the STL file or the SketchUp CAD file here, I hosted the files on Thingiverse. You can download the STL and editable CAD file, and read the installation instructions, at http://www.thingiver...m/thing:1621677 .

 

 

 

What?! Zack the Mack?!

[Draconis]

Well thanks! Now I don't have to do it. Would you think about making a variation for the 1/2" Lee's tubing, with the 9/16" (0.5625) OD?

To add on what Draconis said, what about a 17/32" brass insert variation? 

 

Regardless, I've really only seen one other 3d printed turret designed for new barrel material inserts, and that maker hasn't released the files (and is in Singapore). You've released this to anyone and everyone. Great work!

I added .stl files as an allowable file extension, let me know if you need any others, or if it gives you any trouble.

Langley adding stls will be a great new way instead of things like thingiverse and google drive.

Some day, I'll remake the model in OpenSCAD so I can upload a parametric model to Thingiverse. That will let you customize the model to fit your barrel of choice. If you want to move faster, you can download the SketchUp .skp file from the link in the first post and tweak it yourself.

I tried to attach the .stl file, but it said I wasn't allowed to post that type of file.

Stl files are editable if you make a copy in the right firmware...

Okay, so I downloaded the file and printed one of these turrets.  It looks great, by the way. I like the styling with the open section allowing you to see the darts.  What I had not realized until now is that there are only five barrels.  This would be really awesome if it had seven, like some of the other printable cylinders.

You should make a 6 dart barrel for this gun I would buy 2

[Zack the Mack]

It is a five-round cylinder. Increasing the capacity would require a new ratchet mechanism, which is beyond SketchUp's capabilities... and probably mine!

Mind posting a pic, Drac? I'm curious how it looks in other colors.

Unless I misunderstood, you put PETG into holes made to be filled with it? If so, 7 holes seems like it would take more space than other 7 shot cylinders.

Probably, yes, though I am fairly certain that one of the Singaporean (?) nerfers designed a version for brass.  Also, thin walls could be reinforced by gluing in the barrels.  This would work particularly well with ABS turrets and Lee's tubing, using some universal pipe weld.

You can edit STL files in Blender. The interface can be pretty terrible but if all you need to do is widen an existing opening the boolean function can be used for that.

Or Sketchup, or Fusion. All three are free (Fusion is free on a free yearly subscription for us as hobbyists). I'd avoid Blender for 3d printing, it's so hard for the uninitiated to use.

FTFY. Sketchup is capable of the task.

Yeah, Zaurk0 did this one. https://www.facebook...?type=3

 

I personally have no problem with a 5-shot turret however.

 FTFY. Sketchup is capable of the task.

 

I've never been able to efficiently work with undercuts in curved surfaces with SketchUp.

 

The ratchet isn't hard to model, but it will be hard to modify and tweak. Some day I'll model it in SCAD, which does this trivially.

You need to use plugins man! Off the top of my head, toolsonsurface and jointpushpull should do what you want, I've probably got a few others that'd help. Or do a revolution of the thing, stock sketchup tools can do that easy.

 

To be fair, I've got Sketchup Pro and it has solid tools, which does make it way easier.

Slug fixed the issue with attaching STL files.  You should be able to attach it directly to the post now.  Also zip files are a valid file type.
