M12 | Shotgun Prop

I had the FOREND Part 1 fail (fall) around 3-4 hours in and only picked up hours later (lots of spaghetti :( ), so trying do them separately and added some more forced supports to hopefully keep them up. I can't seem to find all the parts that go into the Actuator Arm Rod, are they present in the current model?

The designer has replied

The actuator arm rod is a steel shaft that is bought, it's both too short and too thin to be printable and hold itself against the pressure of the springs. That being said, if you don't care about the lifter interacting with the bolt (lifting shells when chambering) or being spring loaded (returning to the 'down' position), it's not required The only part printed for the rod is a bushing that is glued onto the shaft and acts as a linear limiter, which is found in the default profile.

Replying to @Vissidus :

ah okay. Great modeling, but unfortunately the print profiles aren't ideal. No brim on large tall objects (PLATE 1), is just wasteful and prone to failure. Had it fall at the 3.5 hour mark of a 4 hour print, and then take out the other. PLATE 4 with the large object and minimal plate point prone to failure, had that fail 4 hours in of a 11 hour print. PLATE 6 bolt charge handle set to the small point and not the opposite, prone to failure (failed in my print) and then PLATE 7 and no brim and lots of high activity and log print time of the small plate base resulted in failure. Most of those would be solved with a better bed brim or base for the object to be more secure during long prints. I've wasted at least 300-400g of filament on multiple print failures at long periods into a print. Sadly I guess I'll need to cut my losses, I don't have another 19 hours and 425g of filament, with the chance of all failures again.

Replying to @Rumbaar :

As noted in the printing profile description, it's been tested on an X1C with specific environment, chamber parameters and material. Your mileage may vary depending on different settings, which is something you need to account for, especially after experiencing failure. Unless you're printing enclosed, even the P1s will require modifications. I'm sorry you had multiple failures on some of the parts, but the choice of orientation stems not only from printing standpoint but from assembly and post processing considerations as well.

@BouncingBall

Do you have plan for a full-stock attachment? Btw nice model again.

The designer has replied

What do you mean by a "full-stock attachment"?

@BouncingBall

Replying to @Vissidus :

Something like this. Idk what it's called.

Replying to @BouncingBall :

Um, yea, that's possible

@user_1405874875

Would it be acceptable to replace the M4×25 and M4×35 screws with M4×30 screws instead?

The designer has replied

I'll update the BOM after comparing against the parts, there's probably a mistake, 25s don't sound right I'll update with another comment when it's done

@user_1405874875

Replying to @Vissidus :

ok thank you

Replying to @user_1405874875 :

I've reviewed the model, and the screws are as follows: The M4x25mm is for the handgrip only, and the screw is behind the trigger and there isn't enough space for anything longer than 25mm. If need be, you can print a spacer for the screw (like a washer) and use a 30mm or 35mm screw with the spacer as is. The 35mm can be replaced with a 30mm screw if the charging handle extension is modified, but the current length is what I found around the minimum what I'd say is comfortable to interact with.

@bigzed

Are all the parts movable or are they exact replicas?

The designer has replied

Some parts are moveable (trigger, safety, hammer, bolt, shell interruptor, shell lifter) They just don't have any function behind them due to raised safety regulations It's not a replica as it is my own design

@bigzed

Replying to @Vissidus :

thanks It would be great if you could also make a short pump version using the Wire method.

Replying to @bigzed :

Not sure what you mean by "wire method", but it's in the works

@Jakeee

hey vissidus what hapened to the 2k11 c2 model did you take it down or the makerworld took it down

The designer has replied

Revoked by MakerWorld, unfortunately. I'm reworking the models in hopes the new revision is compliant with the guidelines which, also unfortunately, provide no clear criteria as to what is allowed and what is forbidden.

@FGa114514

Replying to @Vissidus :

I really want the 2k11 model. Can you send me a copy?

Replying to @FGa114514 :

It's available on my discord server for now

I’m working at the world shooting center in Illinois and I have seen one but with wood furniture and this model is is exactly like it

The designer has replied

Would've be awesome if you could upload a picture of the one at the complex

if I see it again I will

well I think it was one it looked very similar

Print Profile

Default Profile

Great model design, but have a number of changes I'd suggest for anyone printing this on a P2S or in general. To avoid higher risk for print failures. Plate 1: Rotate 180 degree the Magazine Tube Part 1, and enable tree supports. Which will hardish to remove, but I had that fail twice at the top thread in original setup Plate 4: As it's set to 100% infill, and had failure of FOREND Part 1, I rotated them to flat straight up, and still had a failure in the last 30 layers, but used as is. You'll get print artifacts at the minimum section throughout that part in either config (flat or ~45 degree) Plate 6: Swap the BOLT charger handle 180 degree so the larger section is on the plate, as had it fall over with the small end on the bed. Plate 7: Had the Handgrip failed twice, and had to swap it to have the bottom to the bed. Most of the failures were at the fuzzy edge and infill knocking it over.

you're welcome. looking forward to seeing more models from you

could you make a Winchester model 1897 please and it’s okay if you really don’t want to make one

The designer has replied

I'm not a fan of these really old repeating arms, so most likely not, seeing there's already a great one available for download

(Edited)

thanks

the only ones I found can’t be loaded or shell eject by it’s okay I can make it work

Thank you just finished printing and came out perfect
