Custom MA2B Prop Build

[40MikeActual]

Hey there everyone Mike here! This is going to my thread for a 3d print build of the MA2B from one of the halo books/comics. I'm not quite sure which one however here is one of the panels for a reference image. Also, I take no credit for the 3d design of this prop. I am only printing this out for personal use to pair with my Rakshasa armor set that I am making.

(Model by: Lobbster Cosplay)


Stock printed out. No major issues with this one and sanding should be relatively easy.

Magazine printed out. This is when my printer problems started you can see the bottom of this one is fairly messed up and will require a reprint or major sanding to flatten out.

From left to right: Bolt, Flashlight, Trigger, Non-suppressed barrel variant (I will not be using this one, however I may in the future so I printed it out.), and the Scope.
No major issues with any of these ether, sanding should be relatively easy.

Suppressor printed out 2/11/2024, 20 hours print time roughly 250g of filament. Sorry I did not format the other parts like this one, I do not have anything written down for those. Also, my leg for scale. This thing is absolutely massive. I am extremely happy with this print, as my printer was essentially dead for 2 weeks due to a clog. I ended up ordering a tool and now I've cleared the clog and changed nozzle so it seems we are back in business. This prop should be completely printed out in about a week if everything goes smoothly. More updates to come!

Must be trying to get brownie points with Rock Lobbster huh? Looking great so far, gotta get mine done here one of these days!

I approve of the leg for scale.

Update One: 2/13/2024:
I've done it! My printer is back in action! I got this to print finally! This is my third attempt at printing this receiver part for the MA2B. I may take pictures of the failed parts and add them to this update later today, as when I'm typing this It is 2:49 AM and I am just awake and have been removing supports from this part for about half an hour.

Some of the sides may look a bit bad, but the pictures don't do it justice. This should be perfectly fine with some sanding.




The failed prints of this part. Currently one of them is being used as a stand for my new security cam I am using to remotely monitor my prints.

Update Two: 2/14/2024:
Another day, another print! The magwell is complete! This one took 1 day and 4 hours to print. I have one part left to go for this project. I may start sanding my parts down soon while this last part prints, as it is the longest one sitting at 2 days 17 hours and will consume an estimated 753g of filament.
Although, this might wait for a day or two as I will be printing some smaller things unrelated to this project. I've bought a camera to monitor my prints remotely so I don't have to walk through a family member's room to get to my back yard from inside the house to access the shed where I operate my printer out of. If that makes any sense. Anyway, I am printing out a wall mount for that new camera next.
Also I've added on to update one to include pictures of the failed prints of that part.

Print is looking great!

So. This took 3 days to print and an entire portion shifted. I did not notice due to all the supports around the bottom. So, now it lives in the trash can in my shed. This happened on 2/18/2024. I only just now took pictures of it because of how angry it made me.

If you measure where it went wrong you can try and pull off the layer-shifted part and print the last of what was meant to be on this part and glue it on. It'll save you wasting a LOAD of filament.
Best of luck!

oof, those always hurt. Roll and recover, you got this.

There are other parts not visible in these pictures that have holes in them as well and those would be too much to repair, releveling, using glue sticks to make sure bed adhesion is good is probably my best go right now. I am not too angry at the wasted filament, I'm also going to adjust my Z offset and make sure my first layers are good before reprinting. I wish this was a cut and dry fix, but I'll figure it out.

Oof, that's a pretty bad layer shift. Are your belts in good condition / have proper tension?

So, I checked and my bed is not properly leveled anymore, also the belts were in fact more loose than last time I checked. My plan is this weekend to fix my printer issues, do some test prints to make sure everything is all good.
