I swear I had one as a kid, now after 30 minutes of searching, I can't find one or figure out what they are called.

About 1" long, 3/8" around, 1/8" hole lengthwise. Inside is smooth bore. Outside is like a nut, 6 sided. One hole drilled and tapped through one of the 6 sides. Then a "finger screw," which was a threaded rod, with a flat axial area that you used your fingers to twist the screw in. Kinda like a guitar tuning flat thing.

Slide on your launch rod, lock the screw, acts to hold the rocket off the pad.

I can't fine one or the name....help?

Oops, looks like kuririn got there a bit faster than I did, rendering the following irrelevant unless you're trying to save money. I found the same source as he did, using an image source.

I find this gadget rather elegant, and cheaper:

kuririn got there first once again, except this is for just one of those.

Haven't found it yet, but I immediately found this:
https://www.midwayusa.com/product/1014835789
Maybe a bit hefty for a 1/8" rod, but usable, I think.

A search on this may get you close:
1/8" cable stop setscrew
or this:
1/8" shaft setcrew collar
You might have to get your own thumbscrew, though. (NOT finger screw)

Niiiice...very helpful!!!!!!

For lightweight rockets that would use a 1/8" launch rod, you might get away with an Oring that is tight on the rod and a washer that won't go over the Oring. Adjustable, won't damage anything, cheap and easily replaceable parts.
 
I think I'd use a brass or aluminum thumb screw. Alternatively, I might just make a lump of solder on the end of a steel thumb screw. Unless the threads were big enough that it was unlikely I'd over-torque the nylon and break it. Preferably plumber's solder, i.e. non-toxic and probably stronger.

Or several o-rings, or the right size RC silicone fuel tubing, or.....

I have some pieces of aluminum tubing with an ID just over 1/8" and various lengths. Just drop the right one over the launch rod; the launch lug rests on the tube.

This sounds simple and no-fuss. I might try this with my 1/4" lug rockets at this weekend's launch if I can find some 1/4" I.D. metal tubing.

I got the pic from Odd'l....but I couldn't find a dealer. THANKS!

Like to get one that will go up to 1/4".

Vendors for sale of the Odd'l rockets Adeptor are:
JonRocket.com, Apogeerockets.com, Erockets.biz and Siriusrocketry.com

The Adeptor fits 1/8" and 3/16" launch rod diameters.
1/8A through E engines.
I wouldn't recommend any larger motors if mounted on a plastic camera tripod.
The whole idea behind the Adeptor was so I didn't have to be on the ground
when connecting up the micro clips.
 
Two different things are being discussed. The Adeptor allows you to use a tripod as a launch pad. For a standoff to keep a rocket off the blast deflector, you want the Raise Spring from Odd'l Rockets.

I'm pretty sure the adapter as shown in the illustration will do a fine job to keep the rocket high enough on the rod.
 
It's a little known fact that clothespins have legs and occasionally wander off to parts unknown. It's theorized that they are uncomfortable around large groups of people.

Maybe a rare earth magnet could do the job, at least if thet was one that didn't also have legs. Keep away from wallet, phone, and Eggtimer.

The Adeptor has one end threaded to fit a standard tripod mount. A 1/8" or 3/16" rod goes in the other end to allow you to connect a launch rod to a standard tripod mount and use the tripod as a launch pad.

​

Note that the Adeptor is under the blast deflector. See: https://www.rocketreviews.com/oddl-rockets-adeptor-other-by-tom-markel.html

If you want a stand-off, check out the Raise accessory: https://www.rocketreviews.com/oddl-rockets-raise-by-chan-stevens.html

The last lifetime supply of clothespins I bought ‘featured’ springs so weak I doubt that they would secure doll clothes let alone support rockets. Without getting deep, the race to the bottom for commodity items is maddening.

*FLASHBACK*
One of these came with the Centuri Screaming Eagle starter kit! I'd forgotten all about it. Was very handy, but it did corrode quickly.

Now that is a great idea! Time to break out the Manfrotto to make ignitor clips easier to attach.
