Nicely done, lads!  I would be interested as well for a 1.5" bore unit.  Thanks!

Hey Everybody! I've added this to the site to make ordering easier: https://mediablackou...rland-wrap-grip

 

I've added the Shapeways prices for comparison.

 

Tim, you should post a PayPal.Me link to help with donations. Just go to https://paypal.me to set yours up. I'll add that link to my product page once you set it up.

Just got mine from Media Blackout- going to try to use it as a regular post grip for my 3A gimbal. I had been looking into trying to make a few of these ( aluminum) but this might just work! A bit on the thick side but I'll see how it goes. Added grip tape and it feels/ looks great.

Tim- do you think you can design a slimmer one more like the aluminum one pictured?203db9d422ba5f0156bd075eb71ded44.jpg

The issue with going thinner is I can't make threads in a 3d printed part, and the square nuts are all the same size. The whole design is that thick to accommodate the square nuts.

Due to printing minimum wall thickness, it pretty much has to be this size. But nylon can probably be sanded down on the outside if you want to try making it a little smaller.

I tried to find another way to do it for 2" posts byt haven't come up with an alternate way to attach the parts.

Tim - have you thought about adding helicoiled threads? It would require a few post-printing steps, but still be much cheaper than traditional machining, and using a Helicoil or a threaded insert (some of which are specifically designed for insertion into soft plastic) would be more than strong enough for the forces we are applying to this part, and be much lower profile.

Man, would be so cool if someone could invent a super slim wrap grip for a 2" post!

If I do helicoils I may be able to make them thinner for both 1.5 and 2" posts. The issue is they wouldn't be user printable, I'd have to buy a tool and do them on demand.

What would be the maximum thickness desired for 2" and 1.5" posts? A few people have sent me paypal - thanks! I can use that money for a helicoil tool and make a few up.

I'd probably have to charge minimum $60-75 per grip to make it worth my time. Turnaround would be longer, but I could leave my current grips available for people who don't need really thin ones.

Would anybody be interested in that?

Helicoils pull out of 3D printed materials pretty easily. I use mold-in inserts, or use my machines "over molding" feature to embed extra-thin hex nuts, but that's no good for do-it-yourselfers.

You might be better off just using some thread-forming Plastite screws and forgo the threaded inserts altogether.

Ok, after some more playing around, it looks like the thinnest option I can do for a 2 inch post is 2.33". I'll have to get them printed in SLS and put helicoils in.,as well as order specialty small head screws, which would be slotted. I will assemble and ship to you once I receive it.

Because of all this, cost would be $140 shipped in the US for a complete 2piece grip 3.5" tall.

If you're interested, please send me a PM. I'll need 2 people interested to get this started.

Thanks.
Tim
