Here is my 3d printable shareware low mode wrap grip project. If you make one for yourself and find it useful please consider sending a paypal donation my way at lisselandtim [at] Gmail [dot] com.

I wanted to buy a wrap grip for low mode but couldn't find any for sale. So I created my own version that can be 3d printed.

The design is for a 1.5" post, clears the fork of my pro vz gimbal just fine.

Both halves are identical, so you want to print 2 to make one grip. There are small tabs for alignment and slots for square nuts and 10-32 screws. You'll need 2 10/32 square nuts and two 10-32 x 1/2" Allen drive screws. Optionally you can grab some grip tape such as this
Grip Tape from Amazon

Outer Diameter is 62mm, or 2.55".  Due to the size of the square nuts, it had to be this big to accomodate a 2mm wall thickness.

Here are a few photos from Joel San Juan who helped me out testing.

Here are the links.  They are on Tinkercad, where you can download the printable file in your chosen format or upload straight to a service like shapeways or 3d hubs.

If you're in LA, contact Alan Rancher at Media Blackout for printing.
 
4"
4" Wrap grip half
 
3"
3" wrap grip half
 
2"
2" Wrap grip half
 
 These come out somewhere from $20 to $50 per half to get printed. I would recommend going with nylon or PETG at max 100 microns. The black prototype printed at the top of the page is 300 microns ABS, neither of which are ideal.

Let me know what you think.

If you go to the link to tinkercad, you can click to order through 3d hubs and find a local 3d printer.

Or, if you want to just get in touch with media blackout, point them go this thread for links to the size you want, they'll get them printed up nicely for you.

I'm too busy to deal with shipping these other, that's why I provided links. If you feel like it, my paypal email is in the first post.

This is the new age of Steadicam. Thank you for posting this. I fly a two inch post, but this openness reminds me of the old Steadicam forum!

I checked with Alan at Media Blackout, and he gave me the following prices for them to print these out in white Nylon.

2" (two halves) - $27.33
3" (two halves) - $40.41
4" (two halves) - $54.63

Pretty excellent prices, so if you're interested, contact Media Blackout. And let me know here how they work for you.

Is it possible to design a slim version of this for a 2" carbon fiber post?

I could try to make one for 2" posts, I would probably have to use #4-40 screws because the thickness is determined by the square nut that goes on each side.
How big would you want the outer diameter for a 2" post? I'd have to work out the minimum but I'd say about 2.7" give or take.

I'd say it should be as thin as possible and maintain it's structural integrity. 2.7" O.D. sounds good. Can it be slimmer?

I think there would be a good amount of people interested in this. I for one dislike having to grab my post directly when in low mode. Especially if my hands are dirty or sweaty. The post is slick too, no traction for your fingers. Would be great to have a wrap grip for that.

Is there any way to give it a "knurled" finish or something more grippy? Maybe some grip tape would do it.

Can you measure the O.D. Of your gimbal grip, and the space between the forks on the gimbal when angled over the post, to make sure it will fit in that space?

If you tell me the diameter of the grip on the gimbal I'll try to get it as close to that as I can.

Hey Tim, 

Just took some calipers to the post. The post is exactly 2.00" O.D., but the O.D. of the Gimbal handle (sadly) is only 2.15". To match that would be pretty tricky.

And now that I'm picturing it, 2.7" O.D. for the gimbal grip is probably way too wide. 2.2 maybe 2.3 tops, beyond that will just be too fat, I think, and change the feel of the grip too much. Is there any way to 3D print something that slim? And still figure a way to clamp it on and off? It would have to be about 0.2" thick!

 

To answer your other question about the space between the forks. I have an MK-V sled and to dock the rig right side up with a low mode wrap grip above the gimbal, you'd need like almost an inch between the docking collar and the end of the grip. This defeats the purpose for me. Personally I like to keep as short a post as possible, low mode included. So I wouldn't worry about trying to dock the rig in high mode with a wrap grip on. When I'm done with low mode, I would remove the wrap grip, then flip the rig and dock it upright. In low mode I'd want as much grip area below the gimbal as possible and as short a post as possible. So to answer your question, I would just want a 3" wrap grip that I'd slap on the post to take up that whole 3" between the gimbal and docking collar. And I'd forgo the capability of clearing the forks to dock in high mode. If I want to dock in high mode and keep the wrap grip on, I'd extend the post an extra inch to allow me to do that.

Does that make sense? This is just my personal preference though. Others are free to chime in.

I'll have a look tomorrow. I have an idea how I might be able to make it tool less and keep it thin, maybe around 2.25".

Ill take a look and let you know.

I played around with it, it's just so thin that I can't get anything threaded in there. I tried to come up with some sort of clip to make but nothing will be solid or secure enough with that thin of a wall. The grip you want is only .15" thick on each side max, which is really quite thin.

What I could do is probably flare out the top and bottom so that they are thick enough to get small screws in, a little more than 1/4" thick on each side. That would require 4 screws, but it could work.

What is the thickest O.D. Of the gimbal between the forks? That way I would know what I have to work with up there on the flared part.

I'll be out of town a bit next week so maybe I can give it a go this weekend.
