A hand held or base mounted steady cam for the GoPro Hero 3.

This is unusual because it is servo/motor free and there is no counter balance underslung weight either. The vibrations and pitch/roll are dampened out by the use of an overhead pot, filled with a suitable easily sourced medium (see instructions).

Originally designed for mounting onto my DJI 450 Quadcopter, however with the addition of the clip in handle (removable), it becomes a hand held steady cam too.

I designed and printed this as a proof of concept. I wanted to push further the idea of a print in place assembly for the main body component, and to inspire.

EDIT 15/05/2014 : Uploaded STEP file of the assembly, in case anyone wants to make any edits.



Add an M5 x 40 screw and nut.

Everything except the "Waggle Stick Clamp" can be printed without support. However the handle may benefit from support due to the fillets for grip comfort.

GoPro_Gimbal_Mount_Base.stl has two bits of support modelled for the holes at the base of the pot which can easily be removed with a craft knife.

Seems a bit "notchy" at first but it does bed in and become smoother over time. I'm sure a bearing version would be super smooth. A little olive oil helps too.

Fill the pot to suitable height with suitable medium, bit of trial and error for this one, eg :

  • Polystyrene beads
  • Necklace beads
  • Plastic ball bearings
  • Pasta balls
  • Memory foam
  • 1 x GoPro_Gimbal_Mount_Base.stl
  • 1 x GoPro_Waggle_Stick_Clamp.stl (100% infill)
  • 1 x Seal.stl
  • 2 x GoPro_Hero_3_Bump_Guard.stl (100% infill)
  • 2 x Bush.stl
  • 1 x Handle.stl
  • 2 x Pin.stl

Hi I'm not good with Cad but I was wondering if there was a way I could put bearings in the gimbal?

I am having issues printing the gopro_gimbal_mount_base. The flip open lid ends up being sliced as one single piece. every program I view it in there is a barely noticeable gap between the pot and lid. If you uploaded a file where the lid was down like in the picture of the model on the buildplate, that would be great!

Whoops my bad, sorry, I have re-uploaded in the correct print orientation (i.e. with the lid open)

Thanks for the quick reply! Will print it tonight!

will this work for my hero 4 session?

How do you cut open the top? A exacto is having trouble>

did it work for H9SE ? if yes I love you

Hi, after printing the mount base I was able to yet the yoke to rotate freely, but the lid was completely stuck. Any tips to keep this from happening when I print it again? Thanks!

I cant find the instructions that you mentioned in the summary

something like this for an iphone would be sweet!

does anyone have video of this?

I love this thing i just wish i wouldnt get caught on the bottom but great design any tips

I have added chamfers to the bottom of the yoke cylinder so for those peeps who have overly squashed their first layer there should be less chance of fusing the yoke to the body.

For the life of me I cannot get the movable parts on the Gimbal Mount Base to move. I have printed this part 4 times now while adjusting various settings each time. But I break the lid and swing arms off anytime I try to move them. I'm using a Prusa i3, any suggestions would be greatly appreciated. This is a great concept and I can't wait to try it out... if I can get it to print correctly.

I used the tip od a sharp knife to dig a trench following the circle at the back of the part. That is where it was run together and sticking 4 me.

It seems like it can't roll sidewards isn't it?

It can pitch and roll but not yaw.

with your permission I leave the link to an adapter for xiaomi yi, designed by me

Will this work without the bump guard. Just want to use the gopro frame.

It should but if you want to use the waterproof case will be a little big and some movement will be restricted.

Awesome Print !!! Your tolerances are excellent !

any comparison videos with and without the printed steadycam?

Does the middel part of the mount base (where you hang the gopro on) bee abel to move,rotate?

Yes, the yoke rotates.

I was planning on building one of these and adapting it to work on my DJI Phantom 1. How well does this design work with fast movements (i.e. does it sway when moved side to side)? Thanks.

It will depend on the dampening medium in the pot and how much you fill it up.

is the arm piece on the base supposed to be able to rotate or is it locked?

There is clearance in the CAD design to enable the yoke (arm) to rotate. A well calibrated printer with the first layer not too squashed would be able to produce this.

welp the one i used apparently wasnt lol. it was a bad print but i was just wondering. ill try to xacto around the circle on the back to see if i can get it loose. thanks

If you have the ability try reducing the flow rate for your perimeters.

so this wouldnt work with the gopro case would it?

It should but it will be a little big and some movement will be restricted.

ill give it a shot. so essentially all I need is to print this and test to see what the best medium to fill the pot is and it should work like a decent steadycam?

Hi guys,

I need your help here. I am trying to print what I se as a very good design.
How ever trying to prinit it I am really wondering how to find the good position. I have a lot of cantilevered parts which can be hardly printed...
(Waggle_Stick_clamp for exemple or even the mount base...)
I am pretty new in 3D printing. Could you enlight me?


It has all been laid out in the best possible orientation for printing the parts separately. I assume you are not trying to print the complete assembly?

No I am not ;-)
I will try like this and see what happens. If u did it...

Awesome Thing! Do you happen to have a Mount that would fit a hero3 Plus?

I have no idea what the differences are, will this mount fit the 3+, are you able to print and try it?

Late reply, but the physical size of the gopro3 and the 3+ is identical, so yes, it will fit them both.

I wish there was something like this for the Samsung s5

Thanks to share!!! really interesting project, my compliment!

Did you continue to play with this concept? I wonder why you didn't publish any source files. That would make working on improvements for others much easier.

Hi, it's on the back burner atm, too busy on other exciting projects, what source files do you need? I can do STEP files?

I see and I can understand this of course. STEP files (or one file with all) would be great. Feel free to email me at frank(at)helmschrott(dot)de if you don't want to publish it here.

STEP file of the assembly (with breakaway support) has been uploaded.

amazing - thanks.

Yes you have to print 2 off bush files and 2 off the bump guards. Try and work out the assembly from my exploded view in the photos, any other queries then let me know.

thank you! I should have finished printing before asking stupid questions, figured it out. haha just put up the photos of it, thanks for the design!

so im in the middle of printing this and it appears that i have to print 2 of the bush.stl files, is this correct? and the bump guard for gopro that was in stl format is the vertical one, is there a horizontal one that I'm missing or? sorry I'm very new to this, but i love figuring it all out!

So did the concept prove out? Post a video of the result.. Thanks for the post.

now for some printed damping medium... :)

Cut up little snippets of filament ;-)

Awesome idea!

That final orange-cutaway picture is incredibly useful in understanding how the design works. I recommend moving it towards the front of the gallery to help make sure people grok the idea! :)

Done thank you, I have fell foul of having too many CAD renders at the forefront instead of photos, but in this case you are correct.

Ooooh smart design, have you tried it yet? How does it work?

As a proof of concept I am very happy with it, Is it better than an under-slung weighted design? Not sure but then this is fully 3D printed (other than the single bolt). The medium you put in the dampening pot will make a difference too, also as mentioned in the instructions, it becomes smoother when "run in".

Gotcha. I like how compact it is compared to the 'under-slung weight' designs I've seen. Nice work as usual :)
