Let's see your 3D printed parts/models/ideas
« on: May 09, 2018, 12:52:38 AM »
I'd like to see what others are doing with 3D printing for their airguns. Printed parts, 3D models of parts, and ideas for airgun parts.

I've been doing CAD for decades, played with small CNC machines, and also lots of manual machining with lathes and mills. Now I have the 3D printer bug. I started with a small $160 Mini Delta printer a couple months ago. I recently got a bigger Delta printer so now ready to attempt some bigger jobs.  I can make a lot of functional parts right at my home office without having to drive to my shop.

Here are a few of mine to get started:


The scrap bin. Unlike laboriously machined parts, I don't mind scrapping a 3D printed part:


A press-on 4" side wheel for a Monstrum 6-24x50 scope. Just small enough to print on the Mini Delta:

Scott,
Would you PLEASE make an inner cassette for the Marauder .177 mags that uses up the wide spacing of the OEM mags 10 shot ... likely get 14 or 15 shots in there ???

15 shot does not look like it would quite fit. Maybe 14 shot, but aluminum would be better for that. I think 12 shot is doable in plastic, maybe 13.

There's a challenge. Create an STL file for a 12 shot insert to fit an otherwise stock Marauder magazine assembly. I'll probably attempt it at some point. Anyone else want to give it a "shot"?

Scott,

Or the "12+1" magazine.

I decided to give it a try. The process and the results:

I reverse engineered the .177 Marauder magazine insert last night while watching TV:


13 pellets looked like it would easily fit in the 3D model:


I printed out out a 12+1 replacement insert:


Stock 10 shot magazine on left. Modified 12+1 on right:


It works and it would be fine except for one issue. Outside the gun, the loaded magazine can lose the 2nd loaded pellet. The loading window is oblong by necessity. With the pellets spaced so close together, two fit in the window opening. The 2nd pellet can fall out if you are not careful. Once inserted into the gun, all good. I load magazines ahead of time, so that problem makes this an unacceptable modification. An 11 shot insert should be OK. A 12 shot magazine might also work. Any more than that would require a simple change to the printed insert, but would also require a new clear cover with a narrower window.

heres one of my more complicated prints, its a holder that mounts to a vigilante and holds 2 25 gram co2 tanks and a manifold .ive never kept a record off all my projects, except in tinkercad where its just files.
another was my 2240 arrow shooter breech seen here, fun and challenging to draw

Nice work on the 12+1 Scott! I'm not a Marauder Guy so can you tell me why the long slot in the clear part?
I'm looking at 3D printers so I'm interested in everyone's work.

If the slot were round rather than oblong, you would need to load pellet #1 tail first through the hole in the other side of the magazine. With the insert now locked in place, you can rotate the cover to load the remaining pellets head first from the cover side.

The oblong slot makes pellet loading easier/faster. With the oblong slot, all pellets, even #1 can be loaded head first through the cover.

Well been doing MRod single shot trays, a scope wheel and LDC baffles as well as these keychains.  Not really a part but I think they are neat.  This one is a gift for a friend of mine so it was personalized.

Magazine holder for Gauntlet.

This turned out to be a much more involved/difficult than I had originally thought it would be. There were several iterations and multiple test prints of the various aspects of the design before the final print.

Final (most recent) CAD layout:


Final (most recent) solid model:


Slicer run:


It ended up OK. Could be improved even more but it's good enough to use now:

Scott,
That is really excellent !!   Even folks with wood stock G2 m-rods would benefit.

Scott,

The adjustable G2 m-rod's cheek riser mechanism and geometry looks fairly straightforward. So it might be a much better candidate for this type of accessory. It could be lower and would look sleeker than the Gauntlet version.

The Gauntlet has a complicated cheek riser and complicated surface geometry. It was difficult to reverse engineer the dimensions of the cheek riser, and then try to blend the surfaces using my 18 year old CAD program. I was originally going to make it non-adjustable with 8 magazine slots, but decided to go the fully adjustable and then was limited to 7 slots. Besides the magazine holders, this cheek piece has more vertical adjustment than the factory Gauntlet (though I don't use/need the vertical adjustment). I'm not really interested in making more of these for the Gauntlet. Now the G2 m-rod - I might try that. Vince has already offered to lend me his G2 Marauder. But it will have to wait as other projects are in the wings.

These are all great-- really considering getting into 3D printing, however I don't have (really) any CAD experience.

Magazine holder for Gen2 M-rod
« Reply #14 on: July 10, 2018, 03:29:00 PM »
I did another magazine holder. This time for a Marauder:



The post are printed as part of the cheek piece. So not as strong as the stock metal posts. It also took a long time to print. Dimensions are not quite right but it still lined up OK after some work with a file and sandpaper.:




If you want a challenging 3D print, here is the STL file that I used for the one pictured. You will need to turn on supports. Make the walls thick so that the posts are strong enough (or use 100% fill). About half the print time was just building up the posts and supports. When finished, use needle nosed pliers to pry out the supports. And a flat jewelers file or pocket knife to scrape off the support remnants. No guarantees on this file:
http://www.scotthull.us/3Dprint/M-rod2-cheek-01.stl

If I did any more for the Marauder, I'd adjust the dimensions and probably make it 1/8"-1/4" taller with metal posts that screw on. And it would likely hold 7 magazines.

Scott H,

Man that magazine cheekpiece is quite impressive!! I think I need to have you take my 14"x14"x16" printer home with you so you can make some larger builds!

If you were interested in selling one or two I think I have a buyer!

doncha hate talented people :)

Been learning Fusion 360, and just bought the new Monoprice printer with the 300x300x 400mm build area. Fusion is WAY easier than Sketchup...... imo.....

Dan,

That is a good size printer you just got. I started with a Mini-delta 110x120mm (print dia x height). Now using a a larger AnyCubic Delta 230x300mm. Big enough for everything I have attempted so far.

Fortunately, I had a jump start on the learning curve as I was big into CAD during the 1980's and 1990's. These newer, cheaper 3D printers open up a lot of design possibilities for parts that would have been extremely difficult (or impossible) to make using other manufacturing methods.

If I had a big enough printer, I'd attempt a rifle stock. Still looking for a 800x200x100mm Cartesian printer.

I started with the Delta too. Price of admission was good, learned alot on it.

GOts lots of ideas, just need to make it happen CADD wise.... lot of 2 steps forward and one back .....

Stocks? yea thats the eventual.
