3D PRINT STRONGER BOLTS (Super Easy!) | Shapr3D Tutorial

There's a MUCH BETTER way to 3D print bolts... Taking inspiration from @MyTechFun , this video breaks down a simple proven design method to create a much stronger 3D printed bolt.
I welcome any feedback, questions, and comments 👍
Thank you for all of your support and feedback!

Alternatively, take a normal bolt and lower it below the bed in the slicer app. It will only print the exposed part of the model.

There is an easier way to transfer the thread to the nut. Simply make the inner hole of the nut .2mm larger than the shaft of the bolt then place the nut over the bolt and use the subtract tool to transfer the thread to the nut. Then grab the entire inner thread of the nut and do an offset face plus .15-.3mm and you won't have to do any math or calculations. You could also do this in reverse and offset face minus on the bolt.

Great tip! Sounds like a great approach. Thanks for sharing 👍

Cool video. Do you have stls of that somewhere?

[@Makethign]

This is just for demonstration/learning purposes 👍

Great video!

Thank you!

Ok, but why do You print the nut the same old direction?

[@TC-hl1ws]

Why 45 degrees? 60 degrees is typical?

Reduced overhang for 3D printing

@@Makethign Got it. I'd suggest also altering the angles of the thread so that it resembles a buttress thread. As a machinist by trade, when I am given a plastic thread to single point thread on a lathe, the thread is always engineered with the buttress thread geometry. Buttress geometry was developed specifically to give plastic threads strength. The threads on the cap of a tube of toothpaste has a buttress thread. I've never seen the 3D printing community implement this thread form which seems puzzling to me.

Super Easy! All you have to do is take a 4 year undergrad program in CAD and you'll be good to go! LMAO. You have skills but to someone like me there isn't anything easy about what you did.

Blender has a built-in (but not enabled by default) add-on called BoltFactory that lets you instantly generate any bolt/nut you want with any parementer in a couple clicks. You can then either boolean it with a cube to substract the part shown in the video or just place it below the bed in the slicer as someone else commented.

There are lots of tutorials in YT for FreeCAD, which is what I recommend. Within a day, you can get to the level where you can do this.
