100mm MT-12 AT Gun

PT-76 · January 28, 2026, 7:42am

I just got Ukraina’s kit maker Spalah’s MT-12 gun.

This is a full resin kit. This means there are no mistakes, if you make one wrong move, there is no turning back. always dryfit first! This type of full resin and 3d printed kits has disadvantages. The major problem is that’s not a definetly for novice modeler. only for expert. Because you have to use Cyanoacrylate glue, and once you make a mistake, it’s very difficult to undo it. But I’m not a expert, of course. but neither newbie modeler.

Anyway, Will he finish it without mistakes? We’ll see about that.

plus, Once I complete this kit, I’ll probably be the first person to complete it.

Nice looking kit!

That’s just gonna scare folks away. You can use PVA for parts with larger flat mating surfaces, it just requires patience. Like waiting during an episode of Heist Joint Security Area for it to set.

What does the instructions look like? Can you show a page?

PT-76 · January 28, 2026, 7:43pm

Instruction are 19 pages.

Thanks! I think this build requires a lot of dry fit. From my experienes with other 3D printed kits, I am afraid that I would damage parts during careless removal from the “sprue”, I wonder if the long gun barrel comes out straight?

PT-76 · January 28, 2026, 7:52pm

Me too, I’m really afraid of removing from sprue. the 3d printed kits are so fragile.

Gun spade and gun shield/barrel are comes out straight. no removal required.

Last year I posted a method for removing very delicate pieces. There is such thing as a “sonic” remover. So I figured out how to do it myself.

Cup your hand over the part(s) so you don’t lose them. With nippers, clip a big piece of the support base, not this thin supports. Very often the snapping will instantly dislodge your piece(s) with no damage.

I’ll try that. Also in Youtube, lots of folks are recommend using a hot water.

So far so goood.

After applying the cyno glue and placed it, Then I grabbed the tweezers to press it down. and in that brief moment, it stuck! How could it happen so quickly! dayum. That breechblock is supposed to be a little lower. Of course, I dryfitted first. man, and I cannot fix that. cuz I’m afraid of breaking the parts, so I leave it that way.

Just in case for the future, how do you remove super glue when it bonds between parts?

jfeenstra · January 30, 2026, 2:19pm

Use superglue debonder. If you let it seep in for a bit it should penetrate enough to soften it up. Might take a couple attempts if lots of glue was used. Virtually every manufacturer of super glue for modellers has a debonder in their product lineup.

Or use your wife’s nail polish remover. Or acetone from your garage.

Fire?

18bravo · January 30, 2026, 4:35pm

I use that for PE. Works like a charm.

PT-76 · January 30, 2026, 6:14pm

Thanks for advice y’all.

Jakko · January 30, 2026, 6:55pm

But test whatever debonder you use on scrap resin first! Some resins dissolve in acetone, for example.

PT-76 · January 31, 2026, 2:25am

I completed the kit. now it’s time to paint. Since there weren’t many parts, it didn’t take long to build.

I’m not sure if anyone will actually build this, but I discovered several precautions and wanted to share them.

Attaching this shield is the most difficult part. You need to be careful when attaching it.

Although I was carefully and delicately, the result ended up like this. I’m sad because there’s no way to undo it. (As advised above, there are products like acetone or super glue removers, but I don’t have them at the moment.)

End of result should look like this.

edit - but wait, come to think of it. that part is automatically folded when the gun barrel is lower or upper position. ohh, I found a solution then. I mean a more convenient method is to ignore the manual, cut this part into two pieces, and then adjust it freely to match the cannon’s angle.

And another thing

The R27 part. You need to set the direction of this part correctly.

Since part R27 is linked with R12 and R29, so if you misalign the R27, you screwed up! Because as mentioned, this is a 3d kit which requires cyno glue. So I suggest install the cannon to the cradle first, and then gluing the part R27 etc.

Pros

It’s my first time building a resin kit, and I was surprised at how easy to assemble.

cons

the previously mentioned gun shield issue

The pins that connects the parts doesn’t fit into the hole because the diameter is exactly the same. Therefore, the pins needs to be modified.

Overall - 7/10

That’s because it’s a 3D-printed kit. If you now go and build a traditional (hand-cast) resin kit, you will probably be surprised and/or disappointed with how much more effort is needed.

PT-76 · January 31, 2026, 10:16am

That makes me kind of scared to try those kits.

Jakko · January 31, 2026, 6:34pm

There’s not really much to be scared of, but you do need to be prepared to do a lot more work on the parts to clean them up, and possibly to get them to fit. Also, I would want to kind of warn you against supporting your own, local manufacturers by buying a Legend resin kit … I’ve not seen many in the flesh, but every one I did see had warped parts, which is not really what you want for your first-ever (or first couple) of resin kits.

18bravo · January 31, 2026, 6:39pm

They had a few issues at one time. I’ve actually worked for them and we corrected a lot of the problems early one. That and the fact that they have excellent service.

Not seen many in the flesh? Yet EVERY one had warped parts? Pray, where did you see these? At a contest?

I myself have built dozens, many of which I posted on the old Armorama, and had an issue with one, which was quickly remedied.
