It's also possible the 3D design violates patent/copyright which selling it can suddenly draw unwanted legal attention. I believe the creator of the open source bullet feeder for Dillon reloading presses pulled it from Thingiverse and stopped distributing over those concerns especially with folks making them to sell. Warhammer designs are apt to get C&Ded and so creators use some humorously creative names to obfuscate what they are.

At least as far as I know, the creator/first uploader of a file gets to set the uses and one of the options is that others can not sell the file or make money from the use of the file.

random one from Thingiverse:


The icons mean Creative commons licence and that if you do anything with it you must attribute the creator. This one, you could make money off of or make a derivative and be good with.

The ammo box one has a no commercial clause and no derivatives. That means that if you are trying to sell the finished print, that they can shut you down from selling it.

Standard clauses, IANAL YMMV. HTH HAND

Huh. That's a bunch of issues I hadn't thought about before. I'd be curious to see how that system holds up in court.

Or how that system holds up when China starts selling your product for a tenth of the price.

It holds up 100% in court honestly. It's just really expensive to go there so generally doesn't. These licenses evolved in the open source software and media worlds, and are very widely used.

You can also contact someone and ask if you can get their permission to sell their thingie and under what terms. It's OK for them as the creator to extend a different agreement to you than the boilerplate for randos.

I have a huge respect for people who can, either through intuition or long experience, just kind of know things relating to what would make a good product and what kind of price would fly.

I know one guy who laser cuts stuff and he has a real knack for that kind of thing and it always impresses me. I'm more of a doer & designer who dabbles in the entrepreneurial end.

Truthfully, the selling side is just trial and error.

My grandmother had a knack for picking up antique silver and finding moneyed buyers. She moved well in that society and turned buying British antiques for the ultra rich into a massive business in the pre-internet days. Sadly, I was far too young to take things over when she died in 2000. (I was seventeen) But with her, she got burned and had things she couldn't sell sometimes. But then things would catch on, like leather trunks. She literally couldn't buy antique leather trunks fast enough, because they sold instantly. Who loving knew THAT would be a big money thing?

Selling toys on Ebay? It's like shooting mortars. Start shooting prices into the ether and see what starts to stick. Adjust pricing upwards or downwards based on interest and speed of sale. The internet has made life as a seller a lot easier, if your product can stand out in rarity or ingenuity.

I think a lot of the 3D printing people, including people in this thread, have a great ability to make niche products that are otherwise either prohibitively expensive or do not exist. I'd love to see someone here start trying to make inroads with selling. The firearms community is small enough that a good product spreads quickly through word of mouth. Some of these scope rings and odd mounts, there might be money in them.

Dogs, don't do it either, even if the police man really tries to train you to do it.



When you're using a Ruger/Buckmark or anything else with a 10 round capacity it's pretty handy because you can dump all the rounds for a magazine out at once rather than having to fish them out. It's one of those things that doesn't matter at all until you try to get ammo out the day you clip your nails.

OTOH the detent part isn't really necessary, you can just hold it at that position.

Resin seems like a poor choice since it likes to shatter into some nice sharp edges when it breaks. I've heard PETG shatters too when it does break for the filament printing side of things. I haven't experienced that yet but I've only printed a few things with the fussy stuff.

Would a light mount similar to this design be reasonable to 3d print?

http://www.hillpeoplegear.com/Produ...135#description

I'm picturing something shorter and more compact with maybe just 1 or 2 picatinny slots on it. Still intended for a lever gun. Maybe with the slots on one side instead of the bottom.

Basically a little more like the old school M14/M16 Surefire barrel band mounts:




But it would probably still have to clamp horizontally like the HPG one since there's not really room to fit the mount between the barrel and tube mag.

My honest answer to "is x mount thing printable" is to try it and see. It'll break or it won't. But if you're willing to make it bigger and chunkier than a metal one I'm guessing it'll be fine

ThinkFear

Sure, I've designed and made a few light mounts and they've all worked out fine. My advice would be to ditch the pic rail and make a direct mount for your light. The closer you can mount it to the rifle, the less sticking out to get hit and the less leverage any impact will have on the mount.

Javid

So pretty much a clamping thing with two diameters and a couple screw recesses. Measure things and I'll happily model one

E: and it wouldn't be terribly hard to make a low profile rail if you have a rail light already, imo

Tyro
Nov 10, 2009


Thanks for the feedback everyone!

Thinkfear - I'm currently thinking of putting a Surefire X300U on it, hence the P rail. But if that works, I wouldn't be opposed to making a dedicated Surefire Scout light mount either. I guess I could always measure the dimensions of the P-rail mounting plate that clips into the X300U and make a mount that just connects directly to the light, but then I would lose the QD feature.

Unfortunately I don't have a 3d printer myself, and I'm currently deployed overseas without access for my guns. I am just planning out poo poo I'd like to do when I get home.

3d printing has been used in hospitals for a while now for a multitude of items. Including Pollypills where they can make patient tailored pill packs of 6 different drugs in one pill. Formlabs really put it out there for practical uses in medical with their SLA printers.

So follow up DIY question, since I still don't have a 3d printer.

I am considering installing a small section of pic rail onto the wooden forend of a Marlin, so I can use a light on it. There are commercial options to replace the forend with mlok, but I was hoping to keep the aesthetic and not spend the money.

I just want a reality check to see if this is feasible and maybe some suggestions.

Basically I want to mount this rail on the wood at the 9 o clock position
https://i.imgur.com/op4Xn1b.jpg

Like so: (I'll have to relieve the back to fit it over the barrel band)

https://i.imgur.com/l3t9dn5.jpg?1


However it's pretty thin. Like barely a quarter inch. The wood is "walnut" but I think it is stained birch.

https://i.imgur.com/uzkryq3.jpg


My initial thought was to use wood screws and just epoxy the rail to the wood, with the epoxy doing most of the work. But the rail has to be easily and repeatably removable, and nothing can be proud of the wood once it's removed, because the barrel band which holds the handguard onto the gun has to slide past it. It doesn't need to hold zero or go back to exactly the same angle since it's just for a light.

So then I thought maybe tee nuts. But there isn't really room for me to hammer those in from the inside of the handguard or inlet the wood, and they probably need to be flush on the inside.

Then I thought, a brass threaded nut insert. Something like this?

The bolts that came with this thing are 10-24, I haven't been able to find an insert that's only 1/4" long that's meant for wood. I found one made for plastic, maybe I could epoxy it in? Or I could just cut down the length of one of the longer ones that's meant for wood so that it sits flush. I found a similar product that's made for gun stocks, threaded 10-32 unfortunately but buying new screws is simple enough. Again though, these inserts are also 1/2" long.

Is this even worth pursuing or is the wood too thin? Is it time to suck it up and spend $180 on a mlok forend?

Is there a minimum distance from the edge of the wood / the barrel band hole that you'd recommend I put my holes? I was going to assume at least the diameter of the hole away from any edges, is that enough space?

Is a threaded insert the way to go or should I revisit the tee nut or do something else altogether?

I do have a backup OEM handguard in case I mangle mine.

Thanks!

Thought about that too but I would still have to inlet the back of the forend.

Maybe I just need to suck it up and buy the mlok handguard.

ThinkFear
Sep 14, 2007



Move the rail back two inches onto the thicker portion of the hand guard. That way you don't have to screw with removing it to clear the barrel band during disassembly. I'd use threaded inserts like these with a little epoxy on the threads. Might need to shorten them a bit depending on the thickness of the wood.

Sure, t nuts are fine, but making a nice flat spot on the inside for the t nut to rest in isn't something I'd recommend as anyone's first gunsmithing project. At least if it not looking like poo poo is a requirement.

I have an old school RCBS case trimmer with the draw screw collets, and it occurred to me the other day to make it less awful to use with a little leverage assistance. Thus I made this handle:
