Summary

See also http://www.thingiverse.com/thing:2165626 for add-ons (I'll include more over time)

I've added a fully assembled door bolt to print.
either complete or just the bolt itself.

I've included a reduced contact sliding bar version to help with prints that seem to be fused together, please let me know if this helps.

Supports not required

I've added two versions with improved support for the ball handle, the previous ones the ball appears to be distorted but not unusable.

If anyone prints these two with improved ball support, can you let me know if this fixes the problem, my printer is out of action for the next week or so.

Print at least 3 perimeters and at least 27% infill or higher.

I would recommend using a raft not a brim.

Don't scale the assembled one down as the tolerances would be too close.

If your printer is like mine, the parts seem slightly stuck together when printed, then you should still be able to free it up.
I just put the front (the end furthest from the bolt pin) across the jaws of an open vice, so the path of the bolt is free to slide, then tap the back end of the bolt bar with a hammer, I used an M8 bolt to drive the bar into the body. Then just work back and forth a few times, and it should free up.

I've added replacement body and receiver with countersunk screw holes.
These are...
"sliding bolt receiver_csk.stl"
and
"sliding bolt body_csk.stl"

This is the sliding door bolt I made for my shed door.

The one in the picture is made from PLA, although ABS would probably be a better choice for outdoors.

I would probably recommend that the parts be made with at least 50% infill.

Assembly should be quite simple. first make sure the slot in the main body will allow the
sliding bolt shaft to slide freely and also check the shaft fits into the blind hole in the sliding bar.

I put a couple of drops of superglue in the hole in the bar, slotted the bar into the main body, lined the hole up with the slot and push the pin into place firmly.
Be careful not to get glue on the outside of the bar!

Please note that the sliding bar is deliberately over long to allow for expansion and contraction of the wood on my shed.

The inside of the main body may require a little cleanup after printing. I used a small wood chisel to clean out the top corners and a little filing around the slot.

I've added a picture of one of a couple I made 65% of original size, so I can say it works perfectly scaled down too.

Hi, yes this can indeed be printed already assembled, just use the assembled stl file in the download it stands the bolt on it's end.
The bolt should work when printed in one piece as the parts have been carefully arranged in their correct places with a clearance space around all of the moving parts plus a built in support I added to allow the ball end of the pin to print without adding any other method of support material, this can be snapped off afterwards.
The design has been oriented to allow it to work, I suggest using a raft to keep everything stable during printing.
However if you're stuck and the assembled print doesn't work for you, there are all the parts here to print and assemble the bolt yourself.

Let me know if you have any problems.
Good luck. and enjoy your journey into the world of 3d printing!

Hi Folks... I have a Monoprint in the post. I am doing my homework and found this wonderful group. I want to make the bolt for my garden box to keep the racoons out! Looking at the files, I thought the operation required was to print each file separately and then assemble the parts. But reading the posts about hammering fused parts suggests one can print the whole latch and it comes apart! I see Bogul did comment on this but curious how the 3D printer can build the thing in one piece. Anyway, thank for the files and idea.

Hi, If it is fused and you cannot free it up, you can print any of the individual parts and assemble manually, all sizes of all parts are the same as the original.
Using cura you can split all parts or use the individual parts.
The only things I can think of regarding the seized part is maybe the nozzle is oozing a little or you're printing too fast.
You are using cooling aren't you?
Brims seem to fuse the bottom of the print a raft is better.
Good luck, let me know how it goes.

I printed one assembled where I could get the bolt out and moving, but it wasn't easy. The last two I've printed it was seized and I ruined the part trying to get them apart. I'm using the one with less contact on the bolt but I think it is touching during the entire build. Would it be best for me to just print the parts separately?

Comments deleted.

Thanks! :)

Ever test how strong it is?

It's not strong with 24% infill and 2 outer layers in PLA. On a cabinet I installed it on, the sliding part bends enough that I'm afraid to snap it. I would go with at least 50% infill and 3 outer layers to make it more structurally sound. If you wanted to use it on an outside gate to keep (for example) a large pet dog from getting out, I'd go with 100% infill just to be safe.

If strength is a problem then it sounds like either you need to print hotter (210 pla) or reduce your layer height and speed or it could be that you are under extruding.
I have printed test bolts in 1 perimeter with very little infill, but they were never bendy.
I have had bendy parts but only when the above conditions were the problem.

Good luck!

Thanks Bogul, actually I print at 50mm/s with an outer wall speed of 14mm/s and 0.2mm layer height at 217C. The problem is probably the filament I'm using. It's Makergeeks PLA and they seem to have changed their formula possibly as of the past month. The sliding part fully extended gives about 2mm when I bend it by hand. Not much - and it goes back immediately and slides perfectly after that. So it definitely works great aside from the slight flex but it's not really a problem that's not easy to fix. It's a great design!

No I can't say I've done any testing, although printed in PLA the parts do feel very strong, I don't think I could break it by hand.
I guess the actual strength is determined by the material you print it in, the infill and shells and the temperature you print at.

I've never had one become damaged.

This is awesome and incredibly functional. Simple designs are sometimes the best to 3d print!

Thank you for sharing your work with the community!

You;re welcome, thanks for the comment, much appreciated!

Superb design and congrats on getting featured. Well deserved.

Thanks for your kind comments, I will say I was amazed when I found out my door bolt was featured,.I still am!

AWESOME!!! Thanks!!

You're welcome. :)

Perfecto. Realizada con todas las piezas horizontales, todas a la vez. Con prusa i3 P3SteelPro de 3Despaña (www.3despana.com). 0`18 mm, PLA 195º, cama caliente 300x200mm 50º, en cristal normal con Laca Nelly extrafuerte, relleno 60%, con soportes. Lo hemos realizado como prueba para comprobar que la impresión a lo largo del eje Y no tenía problemas. Lo siento pero mi nivel de inglés es nulo, estudié francés en las escuela, jeje. Pongo traducción de Google.

Perfect. Made with all the horizontal pieces, all at the same time. With prusa i3 P3SteelPro from 3Despaña (www.3despana.com). 0`18 mm, PLA 195º, warm bed 300x200mm 50º, in normal glass with lacquer Nelly extrafuerte, filling 60%, with supports. We have done this as proof to check that the print along the Y-axis had no problems. I am sorry but my level of English is zero, I studied French in the schools, hehe. I translate from Google.

Gracias por el cumplido, estoy contento de que esto funcione para usted y estoy seguro de que mi español es peor que su inglés (Gracias a Google!)

Thanks for the compliment, I'm pleased this works for you and I'm sure my Spanish is worse than your English (Thanks Google!)

Great design. But i wouldn't use it on doors that needs to be properly locked.. Not because of the design, but because plastic isn't that vandalism-proof :)

Thanks for the compliment.

I see a lot of things on here and this is really nicely done - Great job my friend :)

Bogul - in reply to donovan2580

You're welcome, I wanted to make something simple and functional, and I'm glad you like it :)

No it shouldn't need any support, the top of the main body is easily bridged by the printer, if needed you can clean up the main body with a small file or a small wood chisel.

Does it need supports for printing?

I'd like to see that if you make one. :)

I think I might try this in bronzefill. Really cool!

You're welcome

Thanks very much, it's good to know your designs are appreciated. :)

Simple but ever so practical Print, done well Bogul.

You're very welcome.

like a lot of things on Thingiverse, when you cant find what you need you have to design one yourself.

To be honest I almost didn't post this as I thought there were probably some out there already.
