Get rid of those baby carriers with six amazing new Nemesis Dreadknight conversion and upgrade kits that are ready to order right now.
Let’s be honest, the stock Nemesis Dreadknight looks like it’s giving a toddler a piggyback ride into battle, and once you’ve seen it you can’t unsee it. The good news is you don’t have to live with that baby-carrier cockpit anymore.
There’s a whole spread of Nemesis Dreadknight upgrade kit options out there now, and picking the right one really comes down to three things: whether you want a printable STL you run off at home or a physical kit that shows up in the mail, whether it’s a parts swap that fits the standard plastic GW model or a full replacement you build from scratch, and how handy you are with a hobby knife when it’s time to make it all sit right.
With new rules on the way, now’s a decent time to set your Grey Knights apart, so here’s how the kits stack up and who each one is really for.
If you’ve never swapped a Dreadknight cockpit before, give the tutorial below a look first, because some conversions can get get fiddly when you’re building on the standard plastic kit.
DeamonSlayer-Master Conversion Parts: $4.00
Updated on August 6, 2026, by Rob Baer with refreshed kit-by-kit details, pricing, and where to buy each one.
The DeamonSlayer-Master from Arma Mechanatus is the cheap way out of the baby-carrier problem. For four dollars you get a printable STL that swaps the open cockpit for a fully enclosed, armored torso, so the silhouette goes from toddler taxi to actual grimdark war engine.
It’s 13 parts and the files come pre-supported, so if you already own a resin printer this is close to a press-print-and-go job. That’s really what the four dollars buys you: a fast visual fix that hides the one thing everybody makes fun of, without touching your wallet the way a $36 kit does.
So who’s it for? Anyone on a budget who prints their own bits and just wants the cockpit gone without committing to a full $36 kit. If that’s you, it’s the easiest four dollars you’ll spend on the model.
Where to get it: the STL comes straight from Arma Mechanatus, or if you’d rather not print it yourself, it’s also sold as a physical kit through Pop Goes the Monkey.
DeamonSlayer-Knight MKII: $35.99
The DeamonSlayer-Knight MKII by Antonis Bouras is the step up from that four-dollar fix. It’s an upgrade kit, not a full model, so you’re adding parts onto a standard plastic GW Nemesis Dreadknight rather than building one from scratch.
That’s the part that matters when you’re deciding: you keep the GW model you already own and just convert it, trading the open baby-carrier cockpit for the MKII look. More work than the single-torso Master swap, a lot less than committing to a whole new printed model, so it sits right in the middle on both cost and effort.
Pop Goes The Monkey: Arch Battleknight Carlos Conversion Kit: $35.99
The Arch Battleknight Carlos kit from Pop Goes the Monkey leans knightly, going by the name and the look: arched armor and an enclosed torso instead of the exposed pilot riding out front. If the baby-carrier cockpit is the thing that bugs you most, this is the part it goes after.
The pitch is that it changes the look in minutes, and that mostly holds up because it reads like a drop-in torso swap rather than a full rebuild, so there’s not much cutting to get it seated. Quick, thematic, and it finally gets those pilots under some armor.
DeamonSlayer-Spartan: $35.99
The DeamonSlayer-Spartan trades the sci-fi cockpit for a Spartan-warrior, so think crested helm and heavier plating over a standing-warrior stance instead of a seated pilot. The kit’s own lore leans into ancient-veteran territory, but for building purposes what matters is that silhouette.
This is the one to grab if you’re running a themed Grey Knights force and want the Dreadknight to match a specific look on the shelf. Lean your basing and helm crest into it and it stops reading like a stock model at all.
DeamonSlayer-Samurai: $35.99
The DeamonSlayer-Samurai does the same trick in a different flavor, swapping the cockpit for samurai-styled armor, so you’re looking at layered plating and a helmeted, standing pose instead of the open frame.
It’s the most stylized of the bunch, which makes it an easy pick if you want your Dreadknight to read as a character rather than one more walker in the list. It’s the same $35.99 as the other Pop Goes the Monkey kits, so the call comes down to which look you like, not the price.
DeamonSlayer-Knight (Full Model):
Here’s where it splits from everything above: the DeamonSlayer-Knight (Full Model) is a complete printable model, not a parts kit. You don’t need a GW Nemesis Dreadknight to start with, because this replaces the whole thing instead of converting it.
So the call between this and the MKII upgrade kit is simple. If you already own the plastic Dreadknight and just want to fix the look, the MKII parts do the job. If you’re starting fresh or you want the more intimidating silhouette, the chunkier armor plates, and the articulated posing all in one go, the full model is the one, since you’re building the whole warsuit the way it probably should’ve shipped.
Final Thoughts On These Nemesis Dreadknight Conversion Kits
So which Nemesis Dreadknight upgrade kit actually belongs on your table? It comes down to your budget, your printer, and how far you want to take it.
On a budget or already printing at home, the four-dollar DeamonSlayer-Master is the no-brainer, the fastest and cheapest way to kill the baby-carrier look. Want the quickest physical swap without a full rebuild? The Arch Battleknight and the MKII bolt onto the GW model you already own. Chasing a specific vibe? The Spartan and Samurai are the thematic picks. And if you’d rather skip the plastic kit entirely and print the whole thing, the full DeamonSlayer-Knight is your centerpiece.
Any one of them gets those pilots under some armor and your Dreadknight off the meme list. Pick the look you’ll be happiest painting, because that’s the one that actually ends up on the table.
