3D Model Parts is a US based company that provides design and manufacturing of 3D printed parts for the scale modelling community. Some of their offerings include scale armor, ship, auto and aircraft detailing accessories as well as providing 3D printing services to model suppliers, manufacturers and hobbyists.

Recently I started out on a new modelling venture with the building the USS Arizona in 1/700 scale and was looking to spruce some of the minute detailing of the kit as the traditional 1/700 scale kits can only go so far in providing some of the finely detailed parts, like many of the ship secondary armaments. In one of my blogs on the Model Shipwrights Forum, one of the members showed me some 3D printed parts for the USS Arizona that he was using supplied from 3D Model Parts. I was intrigued with these new parts and thought, since I was already looking to improve the kit; this was great way to start. Taking the plunge, I ordered a couple of items from 3D Model Parts and see for myself how the parts looked. I wanted to take the time to put together a little review of these products and share something new with my ship modelling friends!

1/700 Scale - 5"/25 Caliber, 5"/51 Caliber and .50 Caliber Water-Cooled Machine Guns

1/700 5-inch-25 Guns (8 pcs)

Model No. U708
Quantity - Standard - 8 pieces
Option 2 - 12 Pieces
MSRP - $7.49 - (8 pieces) / $9.95 (12 pieces)

The 1/700 5-inch-25 Guns from 3D Model Parts is a 3D rendered acrylic resin set to replace battleship and cruiser 5"/25 Caliber Mark 10 deck guns. 3D Model Parts offer two sets to choose from an 8-piece and 12-piece sets. The 5"/25 Caliber gun barrels are created separate from the Mark 10 mountings allowing for more detailing and ease of painting of the parts.

This set is sold in a hard, end-opening plastic tube which protects the parts during shipping. The parts are contained altogether on one wafer. It is suggested that all parts be washed before painting and they can be attached to corresponding parts and your model by way of Cyanoacrylate (CA) or White Glue (PVA). The wafer itself has been designed with the turbulence created from light airbrush in mind as the parts are separated accordingly.

1/700 5-inch/51 Caliber Guns - (10 pcs)

Model No. U730
Quantity - 12 pieces
MSRP - $7.49 (12 pieces)

3D Model Parts has recreated the 5"/51 Caliber gun with the P-13 mounting in 1/700 scale. This is to replace the open air deck guns on any US Battleship prior to and leading into the Second World War. As seen with the 5"/25 Caliber guns I mentioned above, the parts are sold in a protective clear plastic tube and the parts are attached to a small plastic wafer.

The level of detailing is an improvement from the soft detail moldings of the kit supplied parts. Each set comes with 12 guns, which is enough to use on many battleship build needing this gun replacement. The same configuration seen on the 5"/25's where the parts are separated on the wafer allows for easier painting with an airbrush.

1/700 .50-Caliber Water-Cooled Machine Guns (Pedestal Mount) - 20 pcs.

Model No. U712
Quantity - 20 pieces
MSRP - $3.95 (20 pieces)

One of the more interesting offering from 3D Model Parts is their 1/700 .50"/90 Caliber BMG M2 Water-Cooled Machine Guns. In this scale, the .50 caliber machine gun was at best a thin plastic rod on a plastic post of a mount. 3D Model Parts has been able to cleanly print a 1/700 scale version with the standard pedestal mount as it was seen on many ships before, during and after the Second World War.

As with the other sets sold from 3D Model Parts, the pieces come in the same clear plastic tube for protection. The parts are all created on one single wafer for easier painting and construction. The gun and pedestals are created separately and will need to be put together before installation. One thing I did notice is that with a slight adjustment in lengthening the barrel, the mounting would work for replicating the 3" flag guns still installed in many of the older battleships before WWII.


I am extremely happy with the fact I took the chance and ordered up a few of these sets of 3D printed 1/700 scale guns from 3D Model Parts. The parts are cleanly rendered and virtually free from any cleanup for the most part. The layout of the parts is a big plus making it much easier to add color when the time comes. I cannot forget about the value of these little gems; for under $20 US you can resupply your 1/700 scale WWII era battleship with some amazing crisp detailing...and that is including shipping by the way. 3D Model Parts does calculate shipping to each customer individually giving the best possible option for delivery and pricing. I Highly Recommend these replacement guns for anyone needing to upgrade their soft-molded kit parts.

I would like to thank myself for purchasing these 3D Model Part Naval gun replacements. I would like to give a big thanks to the folks at 3D Model Parts for creating a great looking product at a value price! Please stop by their website soon and check out some of their other great offerings or if you need a hand in having any 3D design and printing done!
Highs: Outstandingly detailed 3D rendered US Naval parts in 1/700 scale.
Lows: Can be brittle being acrylic resin but less than cast resin - care in removing parts
Verdict: A welcomed addition to the list of 1/700 scale US Naval aftermarket parts! Highly detailed and value priced
Percentage Rating

About Todd Michalak (TRM5150)

I am building what I like, when I like and how I like it; having fun doing it. I have been building and finishing models on and off my whole life but the past ten years things really exploded. Just about anything goes when it comes to hitting the bench, but wrecked armor, rusted hulks, ships or ...

They are pretty cool Fred!! I can't wait to paint them up and see what they look like in place!

Looks like interesting stuff and they've got some stuff I'm very tempted by on their website. Looks like they're concentrating on USN and RN accessories. The cage masts, pom-pom guns and Vickers quad 50 sets look very nice.

There is an interesting collection of items to pretty up any number of USN kits. They are just starting out btw. More stuff is bound to come from them in the future. They are open to suggestions too.

It'll be interesting to see what they do next. I wonder if they would be open to doing the powered 20mm turret that the Royal Navy introduced in the last 2 years of the war?

I don't think anything is off the table as long as the design can be done Stephen. I dropped 3D an email letting them know the question is out there. Feel free to contact them yourself if he does not stop by first and inquire about ideas!

The twin 20-mm turret, and also the single Bofors 40-mm version, is definitely on the to-do list! We'll try to keep them pose-able, as well. Just about anything we can get reliable specs/drawings for is possible. Suggestions are most welcome at [email protected] We are working to get a customer-driven design feature up and running in the near future.

That would be fantastic! I need some of the 20's for a conversion of Aoshimas HMS Victorious. Honestly, anything you can make would be very welcome.

I would also highly recommend 3DModelParts products. I have several of their items and they are finely printed with hardly discernable printing lines (visible under magnification), no gunk to scrub off, and easy to paint. Their 1/700 water-cooled .50 cals (with magazines) are incredible!

BTW, Carl, how are the boats and launches for Arizona coming?
