Default 3D printed Hetzer 1/16 KIT

Hi,
this is my second RC tank and it will be my first released model.
As i have said in thread dedicated to T-14 Armata, i am a 3D print guy, not typical modeller.
I am focused to developing the STL files for the 3D printable RC tanks.

So...here is my first WW2 vehicle, and first vehicle intended for the public release.

1/16 Hetzer.




I have spent another 18 months of development with this little german vehicle.
Designed to be widely available, dont need any special machines (lathe etc) or parts for building.
Just basic 3D printer with 0,3mm nozzle.Its not recommended to use 0,4mm nozzle and PLA material.
Have prepared printing and assembly guides, It was a huge task.Assembly guide is really big, containing more than 650 pictures.



You can see both assembly guides here:

Assembly guide:
https://drive.google.com/open?id=18L...cBIiZ1xlfTM2r5

Printing guide:
https://drive.google.com/open?id=1or...lPNBsvGUdBGvZj

Hetzer is full of features and optional parts.

-all hatches openable
-servo controlled vertical and horizontal movement of the canon
-servo controlled recoil
-movable gunners sight coupled with gun
-alternative (simple) canon for low-end control units
-360° rotating machinegun
-ready for easy installation of the smoke generator
-LED light for the front light
-tracks tensioners
-working suspensions (different rated springs for front and rear)
-detachable spare track links
-rubber rims of roadwheels
-IR adaptor for HL/Torro IR battle system
-some of the most detailed parts comes with versions for DLP printers

Here is BOM:


Builded vehicle contain more than 200 printed parts, 240 printed tracks links with pins and 345 pieces of various hardware.

Here you can see some of the internal mechanics:














...and full kit with all hardware:





Have some shaky videos.Sorry for that...

Here you can see gun movement with coaxial gun sight (i love that feature).


...some another shaky video with suspension springs:


and third shaky video with runing Hetzer:


I am very bad with videocamera, as you can see.

Its enough for one post, i think.Just few last pictures of my prototype Hetzer.

Great work! The guts of this kit have many possibilities also!

Excellent looking model, looking forward to more details. Great job putting it all together as kit - it is a huge effort.

Thank you very much, guys.

Files will end up on my own website, i am sure with this.I dont want to use third party website.

I have checked RCU posting rules, but i am still not sure if i am allowed to talk about this commercial project here.
It will be my first release ever, i am still just a hobbyst with regular full-time job but on the other side, technically, i can be seen like a company with regular product.
Dont know about this.Have to ask admin, maybe.There are some restrictions about build threads and announcements for companies.

RC_BobM:
A lot of details are described in assembly/printing guide, something in that poor videos and photos.
What do you want to know exactly?What kind of details?
Be a little bit specific, i can give you all answers.

50koruny,
Sorry perhaps I missed it, but are you planning a kit, or just STL files and bom/manual? Builder would source their own parts using your BOM? What speed controller did you use? Do you think some of the parts can be resin printed? Will builder be able to source some printed parts from you (tracks)? Sorry if I am repeating questions you already answered.
Best regards,
B.

There are two options:

1. printed kit - contain more than 200 printed parts, 240 printed tracks links with pins and 345 pieces of various hardware (complete BOM).
There is everything for the building inside, including 4 servos and drivetrain.
Excepting control unit, receiver, transmitter, battery, smoke and sound effects.

2. STL files for 3D print

I am using Elmod.I love that control unit.Combined with FlySky th9x with OpenTX firmware.
You can use any control unit, there is even optional (simple) gun for older RX-18 and other low-end boards.


Printed tracks are available only for kits.Sorry.
I can print and send some of the another parts for individuals, but please, no tracks
Every single track part must be cleaned by the hand.Its long and hard work.

About that resin printers - YES.Definitely.There is even special group of files for DLP/SLA printers.
There are some of the most detailed parts, reworked to be even more detailed and optimized for DLP.
Including MG-34, early toolbox with holes etc.

I am using DLP/SLA printers even for kit.There is a high number of DLP printed parts.

50koruny,
Thank you, you answered my questions! I have Elegoo Mars printer which is great for detail parts. It might even work for road wheels etc, the new resins are quite hard and strong.

This entire thread has basically been an advertisement, so if they haven't busted you by now I'd say you're good to go. Unless someone complains, you should be fine.

Hi, guys.
there is a lot of work with my webpage and i dont have time to do this for now.
Because of that, i have published STL files on the Cults3D for now.
It will move to my website warprints.xyz when ready.

Here is link:
https://cults3d.com/en/3d-model/vari...-1-16-rc-model

Working on the 1/6 Hetzer right now.
It will be complete rework, not just a simple rescale.
Minimal requirements for the 1/6 Hetzer will be 3d printer with 350x350x350mm buildplate.

Preparing Cromwell too.1/1 scale 3D model is ready, need to work on the rescaling and inner mechanics.
It will be available in muiltiple scales too.
Have leaved my job and i am fully focused on the RC tanks.
Working much faster now.

Very good news, Tomαš! Very interested in that Cromwell along with your ongoing Hetzer work.

So I started one of these as a side project and a learning tool.... I've printed some of the big pieces and started collecting the hardware.... All I can say so far is WOW....

I started ordering the hardware and bearings off the inter web and holy crow, that's a lot of stuff! I'm about $175 in and haven't even got the motors or servos yet! (I'm ordering enough for two so don't be too alarmed yet....)

Im using my Ender 3 pro and the glacis took me 28 hours to print!!!! (I'm adjusting the setting as I go so bear with me!)

Looks great.Thank you for the pictures.
Yes - there is a lot of hardware.
It can be a little bit hard or pricey to get all that hardware, depends on the country.
Right now and here (Slovakia), price of the hardware for one kit is about 58€ (Chinese stuff).
I have still only limited amount of hardware in stock.
Going to order more and more hardware, because i want to offer complete packages to make building easier and cheaper.
Dont want to make money on this, just make things easier and accessible.I hope it will be available soon.

P.S.: Hardware for the 1/6 version will cost 80-90€ (Chinese stuff).

This is the complete list of the hardware for the 1/16 version.

So of course my printer took a giant *&^$#@. In the interim here are some Photos from the Littlefield example when it was here in Phoenix about 2012...

Nice! Love seeing close-ups with details such as that ragged edge of the plate.

I have purchased the tank and I want to try and SL print the tracks in ABS Resin. Any chance of uploading on the purchase site a track link without the support parts? My CAD program is having trouble dealing with the part and I am not up to speed in Fusion 360 yet.
I have already printed some of the detail parts in Resin.
Thanks

Thank you for the buying.Hope you will enjoy printing and building.
Your resin parts looks very good.
Send me your email, please.
Going to send you a STL file for the tracks.

Thank you. I used a Prusa SL1 and cranked it all the way up. The main gun barrel (not shown) was about 4,000 layers! Took 11 hours but I love the quality.

Email sent via private messaging.

Thanks again.

This kit is excellent and i will be taking up the challenge to print one myself
A great piece of work
