Helmet Scaler is the world’s first standalone desktop application built specifically to solve one of the biggest challenges in wearable 3D printing: achieving a perfect helmet fit.
Designed for creators, cosplayers, prop makers, and professionals, Helmet Scaler allows you to precisely scale and position helmets, masks, and similar wearable 3D models—before you ever start printing.
The application is built to feel instantly familiar. From the first launch, the workflow is intuitive, efficient, and designed to feel as if you’ve been using it forever.
Best of all, Helmet Scaler is completely free, made possible by the amazing supporters of the MysteryMakers Patreon.

Helmet Scaler works entirely offline.
It does not connect to the internet, does not collect any data, and does not upload or track anything.
Your facial 3D scans and confidential helmet projects remain fully private and entirely yours.
Helmet Scaler is not a general-purpose 3D tool—it is a purpose-built solution focused entirely on wearable fit accuracy. Every feature exists to save time, reduce failed prints, and deliver professional results consistently.
Perfect fit. Predictable results. Zero cost.

your domain is dead?
it will be solved soon :)
I'm working on scaling a multi piece helmet. Do I just scale all the pieces the exact same amount to ensure they connect?
Combine the parts first - here's a video on hpw to do it :) https://youtu.be/riE4LudW4T4?is=v_uj-e1ntNHINEdC
Can this help scale to allow for glasses?
not at the moment, new features will be added, im just a a solo developer/modeler so i hae to first take care of the web and proejct releaes and when i grab some time i will keep adding new featues :)
Where can I find the Measurement Calipers file? Thanx for all the effort on the software :)
when you download the software in the pakage are the stl files as well :)
amazing
I tried downloading on my Mac and PC, both gave me a 502 Bad Gateway?
Yea at the moment the page is down, my web developer is updating some stuff on the servers, we are preparing the new official web page, so in thr following days its normal to expect some things to randommly go offline, thank you for the patience :)
Is the website no longer live?
works now, I ampreparing the new page as well so my web developer had to do some server updates :)
I just bought two armors, I will be able to work and have fun with them. Great job, fast and efficient!!
Incredible piece of software - great work!!!!
thank you so much :) i have allready listed some upgrades that i wish to make, just need to catch some free time to start implementing it :D its a bit tricky to be a solo designer and do all of it my myself :D but i'll get there :D
clicked to download but no link appeared. I am on MAC btw...
make sure to click download , the page will open, and then click download for MAC OS - just tried it, it works :)
This is what I've been waiting for. Great job!
Well I downloaded it and have been giving it a go, it works really well, and it also made me realize how gigantic my head is...holy cripes
ahahah :D
For some reason it won't open for me on my Mac. It says it can't verify it is free of malware and move to trash.
Got it, nevermind
You are amazing! You solved my biggest trouble!! Thank you!!!
Happy to hear that :)
Fantastic Tool - this is extremely useful! I do appreciate the simplicity in the UX.
thank you :) the goal was to completely avoid any long time learning and just be able to us it straight away :D
So when are we putting in the paperwork to have him canonized as a saint?
awwww, stoop iiiiiit :D haha
Absolutely amazing! My one suggestion is to add an opacity slider for the helmet but this is so helpful with the sizing rings
will look into it, opacity might mess up with other functions, but will see what I can do :)
already used this 3 times today .... absolutely fantastic
yesssss, happy to hear that :D did you also try the calipers ? :)
Beautiful, thanks Marko! What tool did you use to scan your head?
it was a 3d scanner - the revopoint miracle
This is much needed, great job Marko!
thank you. , glad you like it :) will try to do more videos as well :)
Thanks... Can't believe I have been here for over a year. Great work and glad I am here.
thank you :) it means allot :)
Is there any plans to expand this to full body?
it Is possible :D
Thank you!!!
my pleasure :)
This is awesome!!! Knowing you that you always take it one step further i just have to ask. Does this mean that there will be an update for full body?
that is possible :D :D
Love it 👍👍
thank you so much :)
I was just talking to my wife about having trouble sizing helmets to fit. This will help immensly! Thank you!
Happy to hear it will be a great help :) let me know how it goes when you try it out :)
what size is the male head ?
when you ope up the app an click the male/female head, down where the values are you can see the sizing , they are in mm - so 195 x 226 x 229
This is great, so glad I joined your Patreon!
thank you so much :) it does mean a lot:)
Thank you this is AWESOME and so necessary
happy to hear :) was very excited to finally show it to everyone :)
Thank you for this from 3D Printing Guy! The absolute best part is it works on Mac!
haha that one actually gave me some problems so It took a bit longer :D but yes Mac users can benefit from this as well now :)
Excellent work cant wait to try it!
looking forward to some feedback :)
Using the gingerbread as an an example, is there a way to import ears and rangefinder, etc. together with the helmet at the same time and scale those together so they fit?
so you can import 1 stl once - depending on wich scale system you plan to use there are a few solutions - if you use the uniform scale just take note of the scale% and remember it - then type in the same scale % to the other parts and they will match up - if you use non uniform scale generally I dont recommend using non uniform scale when there are multiple parts as offsets might no longer work, but that being said I think I will start adding "grouped" helmet models with smaller parts so it works with this. its all a bit new but the way I will approach all my new releases will be totally in line with this, however you can still use it for the old ones as well
OMG !!! Thank you
my pleasure :)
That looks awesome! I can't wait to try it
thank you :) hope it will be fun to use :)
Wow! This is fantastic! Thank you so much for making this inedible tool, can’t wait to try it out!
im sure you'll have fun with it :) feel free to share some feedback :)
This is awesome, thank you! Now if I can just manage to finally get a 3D scan of my noggin.
haha it will definitely make things easier having a 3d scan ;)
Marko my good sir, first you spoil us with your impeccable models of masks, helmets, armour and props, and now you spoil us with this! Bravo to you!!!!
only the best for my guys :D I love making al of these and you guys deserve it :)
So is this standalone or oart of galactic armorys armor scaling sodtware. So weird that creators are always doing the same things
It’s a standalone project, not connected to any other software. The idea came from my own needs, but I get why it might remind people of similar tools. Please watch the YT video, i talk about it in a bit more detail :)
Well done with this mate congrats and thanks for sharing
my pleasure :) hope it will be fun to use :)
Amazing!!!!!!!!
thank you bud :)
Great work Looks amazing and is nice and straightforward to use. Ive been using refmaker for a while but always been concerned about uploading 3d scans and 3d modles as who know where they are keped or used and this app solves all those issues
Any chance there will be a update for 3mf to keep colour data ?
Uuuhhhh oO Awesome!!! Looks easy and with all the right functions, thank you very much. Cant wait to give it a try ;)
should be pretty fun to use :) let me know what you think :)
Yes! As a member of team big head this is amazing! When will it be released?
I'm dumb. I see the link!
WHAT IN THE HOLY F.....ROG! This is insane! BWAHAHA
thank you :D
Very cool!
thank you John :)
You are amazing!
Thank you sir :)
