Design and 3D Print Knobs for Bolts

Sorry for my raspy voice! Getting over an illness - lost my voice and it’s slowly coming back.
Pretty basic model! If you have any questions or tips/tricks, leave them down in the comments! Thanks for watching!

As part of my 3D printing hobby I've been using Fusion 360 for a couple of years. I am completely self-taught and still learning. Fusion 360 is a great program but it can be daunting by times I found the pace of your video and the narration very easy to follow. Thank you

[@brianmitchell9890]

Awesome video! I always learn so many tips I can apply to completely different projects

[@ShopTherapy623]

I think there’s a lot more benefit watching someone work through a project than watching a video on one specific function. That’s what I’m hoping to achieve with these videos.

[@mdempers1]

I learned a lot in that, thank you for taking the time to put this together in such detail. You have a new subscriber :-)

[@SolidYaz]

what an amazing video!! and the slicing example and fixing the supports!!! phenomenal. I'm learning a lot from you! thankssssssssss

[@JayHuemann]

Thank you. The press/pull tool will be very helpful. I appreciate you showing that tool.

[@ShopTherapy623]

Glad it was helpful!

[@VGMTB]

This is an awesome video!!

[@benjaminsoldan]

Thanks man! You are awesome! Learned in your tutorial more than in 100 other tutorils at all! Reeealy awesome work!

[@vanguardcycle]

i'm learning a ton from these! i didnt know about using the combine tool to cut like that. super helpful

[@ShopTherapy623]

yeah, I think "combine" is kind of a weird name for that tool, since it does other things as well

[@3dprint4u]

Great video, thanks for that.

[@ericheft6184]

Thanks for sharing. I'm new to fusion and 3d printing. Picked up a few new concepts from this.

[@ShopTherapy623]

Glad to hear it!

[@rayxfinkle8328]

I wish fusion was more consistent when selecting a single edge and auto detection the rest of them. Great tutorial, thanks

[@ShopTherapy623]

Yeah they need to take a page out of Blender’s book - hold down “option” and it’ll detect an edge loop and select them all. Doesn’t seem like that would be too difficult to implement.

[@rayxfinkle8328]

@ShopTherapy623 If i remember correctly, autocad does it with a long hover.... I could be wrong

[@KenWmo]

Thank you for this video. I’m a real newbie with fusion and find it more “con-fusion”. Your step by step method lets me follow along and achieve the same results. Very much appreciated! Subscription entered as soon as I finished the video. Too often this type of video says things like “just hide the…” or “make the array…” without showing you how. They feel a lot like my old calculus book where they often stated “the proof is left as an exercise for the student”. I wouldn’t need the book if I could do the proof! BTW, it printed without issue. If you change the cover to have a hole, it would also work to capture a nut and make a female rather than male.

Nice work. You are very thorough; that's rare. All the best in 2025.

[@fyraiett]

Thanks, great tutorial! 👍

When you insert the polygon at the beginning you can put in the math formula 11.1/2

[@ShopTherapy623]

Ahh yes! I knew that, but my brain wasn’t braining! Great tip!

[@stuartansell4027]

Another great tutorial Doug! When you chamfer the plug (20:36), could you invert the chamfer edge to the plug, so it would fit flush on the surface with no gap? Ok I know would then be tough to remove, but just a thought as another option.

[@ShopTherapy623]

Yes, absolutely you can. You could leave those chamfers out and try to get it as snug as possible to try and hide that plug. I come from a woodworking background. In cabinet making, if there’s a seam that’s hard to hide, you actually try and make the seam look like part of the design instead (by chamfering the edges). So that’s what I did here - tried to make the seams look obvious so it looked like part of the design.

[@ChrisBloom]

2:11. A shortcut I like is if you know the diameter, and it's asking for the radius, you can just enter: 11.125/2 it'll do the math and put it in for you. FYI.

Perdona mi ignorancia.. ya llevo algun tiempo con la impresión 3D, y desde que empecé utilizo para fabricar o modelar mis pieza "3D builder" y como cuando comencé en el mundillo del 3D, me parecia todo tan engorroso y difícil, solo dedicaba tiempo a aprender a usar 3D builder.. y si que se pueden hacer algunas cosas si tienes algo de idea y maña.. pero lo veo bastante limitado en comparación con muchos otros programas que veo... y queria hacerte dos preguntas si no te importa.. este programa que usas en el video es "Fusion 360?" Y la otra pregunta seria.. que programa me recomendarias que no fuese muy complicado de usar.. muchísimas gracias de antemano 😊..

[@ShopTherapy623]

Sí, el programa que estoy usando es Autodesk Fusion. Aparte de Google Sketchup, es el único programa que he utilizado para el modelado 3D. Es un programa muy robusto y puede hacer cualquier cosa que quieras que haga. Lo siento, no tengo ningún buen consejo sobre qué otro software usar. Hay una versión gratuita de Fusion que puedes usar, y no es muy difícil de aprender.

[@Rafa.h.]

Mil gracias por responder.. intentare usar esa versión gratuita de Fusion que me dices .. un saludo y gracias de nuevo por la respuesta ​@@ShopTherapy623

I would assume if you are making a knob for a hex bolt, you already have the bolt. Why not just measure the bolt?

[@ShopTherapy623]

Yes, I said that in the beginning of the video - if you have the bolt just measure it. However, not everyone has calipers. I actually didn’t have the bolt when I designed these.
