Snap-in. Snap-out. All grip. No hassle.
This is the SpringDock: Phone Edition — a 100% 3D-printable, snap-together phone holder built with compliant spring arms that grip your phone securely with a simple squeeze-and-release motion. Whether you’re at your desk, in bed, or anywhere else you need a quick dock for your device, this design makes it effortless.
The spring mechanism is printed directly into the body — no metal springs or extra hardware required. Just print, snap it together, and it’s ready to use.
Features:
- Fully 3D printable — no screws or metal parts
- Secure compliant spring grip holds your phone with ease
- One-handed operation: squeeze to open, let go to dock
- Rotatable design for portrait or landscape viewing

Great for desks, bedside tables, studio setups, and anywhere you want your phone easily visible but out of the way.
This is the first in the SpringDock series — future editions may include tablet holders and more.

Hi, thanks for posting the make and the comments/feedback. I will have more options coming. I have someone testing a grip system that is wider and will post that shortly. I also suggest it may be better with my ClampDock mount if you are having stability issues. Thank you.
Small thing I noticed as I'm putting mine together at the moment. "SpringDock 1v00a 611 Index Core.stl" isn't labeled as "(x2)" like the others, so I looked over cloning it
ok, good. I will fix that. Appreciated.
Haha, yes, challenge accepted. Unfortunately, I have a little burnout trying to keep up but I am definitely going to try to make a version with the mag charger in it. Really appreciate you posting the make and the comments.
This is an awesome build. Mine is working very well with clampdock system(also I really love that system). My spring could be a bit tighter on my iphone 14 as it wants to slide out a bit but nothing terrible.
Ok, thanks for the feedback, I will make some variants to give you more grip
This is so impressive. I would love to see a version that can handle a Samsung fold 6 plus with a slim case. Both folded and open.
Can you send me all the relevant dimensions?
This would be awesome, maybe one with some tolerances for various folding phones. I got a fold 5 and would totally give this a shot.
Are you thinking with the fold 5 unfolded? So that would be quite wide but doable. I have never used a folding phone like that so not sure how the pressure from the clamping would affect it. Do you think it would be ok? I mean not case the phone to fold closed.
I tried my hand at making it fit my fold 5. Extended the A & B PETG spring arms by 25mm. It works to hold the phone horizontally, but its a bit vertically challenged due to the diminishing clamping strength from the bit more flex in the length. Might try making the arms one solid unit and maybe add some girth on a second revision. Besides that, this thing is pretty sweet and a heck of a unit, works perfectly with my phone folded
Yeah unfolded would be sweet. I've put this phone through the ringer with no case since I got it about a year ago I believe. I think the average width of folding phones are round 6.2 inches diagonally nowadays.
Would love to see some sort of weighted base for this and your tablet holder. Maybe change the base to be closed and add sand or shot?
Yes, I agree. But no5 sure of the solution. I really like to make designs 100% printable but in these cases a weighted base would be great.
I would love to know how/where you learned the mechanisms? I've always been fascinated by how you know what mechanisms there are and which to use.
I would love to be able to share that and help others design but I do not know how. I guess I have spent a lifetime that started with things like Lego and eventually became woodworking, crafting, working on cars, and fixing office equipment. I studied robotics and industrial automation engineering. I have always been fascinated with machines and have frequently taken apart things to see how they work. So lots of practice and exploration. (continue in next reply)...
I have been asked a lot to try to share what I do so I will try to make time to create some videos or something like that. I just don't know where to start.
Is it g code
