Description

.308/7.62 cut away model. Support is only needed for the primer pocket area on the casing. Recommend to use a brim with most pieces except for the ,"primer anvil." Use superglue to assemble, I like he gel type, best. Scaled at 300%, it is rather large as seen in the photo.

Filaments Used came from CC3D:

PLA Silk- Bronze Brass(Case and anvil)
PLA Silk- Silver( Lead, Primer Cup,Primer Cup Base)
PLA Silk-Copper( Bullet Jacket)
PLA- Any Color, I used dark grey( Primer Compound)
PLA-Black or Dark Grey( Gunpowder)

I love your ammo model designs and how detailed they are. But I'm having some issues with printing the powder for the .308 one. Printing it upright results in build plate separation at around 3/4 of the total height. I've meticulously cleaned the build plate (textured PEI plate) and I'm using an X1C with bed leveling, so Z axis calibration shouldn't be the issue either. I've tried increasing the brim, but it will either break free from the brim, or lift the entire brim with it. I tried printing it laying on the back (with support) and that worked, but due to the texture on the back, the support is extremely difficult to remove. I also tried using the powder piece from the 9mm cartridge and scaling that up (with the smooth back it would be easier to print laying on the back with support), but that one doesn't have the taper at the bottom, so it doesn't properly fit into the .308 case, even when otherwise scaled correctly (the matching pattern on the two indicates, that the 9mm one was a scaled down .308, or based on that anyways). Would it be possible for you to add a version of the .308 powder that uses a smooth back, like the 9mm one?

I think I found a solution to my problem (well, it worked one out of one times so far, so technically 100% of the time XD). I sliced off about 0.3mm off of the bottom, creating a flat base, rather than the textured one that had little contact with the build plate. With a 10mm brim I was able to print it upright without any issues. And it looks much better than the version printed on its back. I'll be printing a couple more of them, will report back how that worked.

I can try to get another version of the powder out. I’ve printed about 70nof these in an X1C without issue, not sure why it’s giving you a hard time.

Replying to @Johnny_No_5 :

I've uploaded my modified powder models here: https://makerworld.com/en/models/501971 If anyone else has this issue, they don't need to mess around with the models themselves. Also feel free to use them as you see fit. They are 99.99% your work anyways :)

A!, 04 nozzle. All PLA Matt. Printed just fine, but took forever since 4 colors on one plate. I believe it prints faster in total of each colormpart iron separate plate. Did some small modifications to be able to show a whole bullet. Added magnets to keep it closed. Let me know if you want to see my print profile.

@Johnny_No_5

looks great! can you upload the modifications? I will edit by color plate. that’s how I printed it, but, I’m still new to uploading files.

Another great model by the designer. Great for firearms enthusiast or as training aids for firearms safety course instructors. Very well designed, parts fit together with precision. The great instructions on proper assembly. I printed two copies of this model, the one on the left uses the filaments listed below and the one on the right used the exact filaments listed by the designer.
