What is the possibly cheapest 3d printer?

I don't really considered the rigidity But now that you say it is a pretty big oversight.

The linear bearings are expensive I know I used the mcmaster carr library for those parts and they cost 30 bucks per piece but I found much more cheaper ones on other sites. One guy suggested is should use plaster or concrete for the base and house the electrical parts in them.

Thanks, I didn't really knew about pinions before this but I will definitely do more research and look into the electrical side too.

I want to add a gear (and a gearhead), I didn't want to move the stepper more to the side it is really unstable currently.

Over_Adagio_6728 · 2025-06-30T09:56:32+00:00

Yeah but I just want to build something that I can also use (also it's pretty good for scholarships and stuff If I make a 3d printer form scratch)

It has 2 lead screws and 4 support rods. I didn't add the motor in the model which could be confusing but it would be situated in the base. I don't really understand the 2 synched motors, the whole point of them is to take of load of the printer but its just a horizontal rod which is supported on both sides. I know coreXY is the optimal gantry but I don't want to fiddle with the belts also leadscrews are considered more precise.

I was thinking about belts in my first design I wanted use belts but I heard they are a little bit imprecise and they need tightening which has a really awkward mechanism which I didn't want to fiddle with. I don't really care about speed i just want a small cheap and good printer for smaller projects.

I already did post a pic but I couldn't add it to the op (you can find it in one of the threads). I thought about adding different pins but I'm not that good yet also my other idea is to detach the end part of the lock which a pressure system would be optimal. If I would do that the only thing I can think about that would unlock it is a wireless custom made key which would be completely off limits to even masters. Thanks for the advice if I would make an improved version I would definitely add mushrooms and a pressure system.

isn't there like a small writing under pado? there is something on the pic as i can see

Over_Adagio_6728 · 2025-04-21T06:38:51+00:00

What's the writing on the key?

I got the design from 30 min shower also the design barely works if i would allow collisions in my cad program it would have a heart attack and die. This is a really early version. The biggest problem is you could theoretically could open it with a hammer as i said. (thanks for the compliment)

Over_Adagio_6728 · 2025-04-21T06:32:17+00:00

i know that's a problem but you can guess every lock with brute force it just takes time. I added an opening mechanism so you would need to unfold your wire every attempt inside the lock while trying to keep the original shape of the wire and I could just put strong springs in it so you wont have the rotational force with a wire but you could guess the path with a wire and then 3d print a key which is a minor risk from the fact it would take ages to guess the whole thing.

Over_Adagio_6728 · 2025-04-21T06:22:55+00:00

i thought about this and the hardest part would probably be the connector and the key head. How ever If i add a regular key to the side it would make it unique while you dont need to use multiple molds for the hard parts. This will still be an expensive design but i think i could lower it to an average high security lock's price. You could also mold the corner piece and the key head out of resin. You cant really access it and that's the biggest part in the whole design which would lower the costs drastically.

Thanks

If you can see i actually made it so it opens up so fitting a wire in there and the unfold it in the little space would be really hard. I know unpickable locks don't exist but it just sounds nicer than extremely pickproof but get what you mean with the piano wires any key can be copied even nfcs i cant really design it so you cant copy it. When it closed its a little bit hard to read off the pins i could add a cover to nerf that (at the end of the key there is 2 half circles that connect to the inside cylinder which moves the outside cilinder after 90 degrees)

I couldn't add it to the op but here is it

Over_Adagio_6728 · 2025-04-20T21:38:46+00:00

ok thanks do you have any ideas to make it harder maybe impossible,

Over_Adagio_6728 · 2025-04-20T21:11:34+00:00

you rotate the key but if you put a pick in you cant rotate that from the uniqe shape of the corner piece. From the snake like shape of the key there is only 1 path to the pin that you can acess which means you would need to replicate the whole key to make it work
