@ianmcc2420 😁 Glad I could give something helpful. It really isn't needed at all as long as its manifold. Some of my projects would make designers for computer games very shocked but it just isn't needed at all.
just a quick engineering tip, bevel (fillet) the root of the tooth so there isn't as much of a stress concentration point. generally the way to do it would be to make it 0.25 of the modulus of the tooth and without going into the details the height of the tooth is roughly 2.25 of the modulus. In your case the tooth is 2,95mm tall so the fillet should have a radius of 0,3279mm but you can round it at 0,32mm.
Great video, thanks! To take the accuracy of the replicated part up a tad, especially if the tooth profile is important, I'd scan the part using a regular office document scanner at say 600dpi, then use that as a reference image in blender.
@kurogiza 👍🏻 I have a 3D scanner so I would have normally used that but I wanted to cover something without using something people might not have access too. But it's a great suggestion for something you can fit flat on it.
@@ArtisansofVaul First off, loved this video and found it really useful. I'd say though that most people with a 3d printer WILL have a desktop scanner and I at least would appreciate another video covering the scanned object approach to fully understand the differences.
@markhickson9087 Maybe. I have a lot of tech but I don't have a scanner. Or a normal printer. So maybe I'm bias based on what I have 😅 I do want to do some things on making specific shapes from 3D scans but it seems quite niche. If there's a desire for it it could be a fun video
@mind_of_a_darkhorse it really depends what you want to print and you're use for it. I have a PLA (plastic) printer and resin printers which are more for miniatures. What you looking to do?
It always kills me that blender asks for the radius in the operator panel but shows essentially the diameter in the item properties (because bounding box). I think at least half the time I make something round, it comes out twice as big as I wanted. :-) I do wish there was an easy way to scale something such that its bounding box is a certain absolute size, but I haven't found any good way to do that. Even CAD Transforms makes that difficult, because it won't scale symmetrically when you use that. (At least as I've found.) I'm definitely going to have to look into ND - that looks pretty handy!
@darrennew8211 I'm not home to be able to try it out but maybe using the scaling box tool, which seems to work from the bounding box, is the answer. Not sure if you can type in an answer. Also when you use the scale tool I can't remember if there's an option in the box to set as using the bounding box....?
@@ArtisansofVaul I haven't gotten either tool to take a unit of measurement as an input. The scale box seems to let you scale in a certain direction (e.g., half as wide but move the right side and not the left) but it doesn't allow for absolute distances like the move tool does. As far as I can find, at least. I usually put in a MeasureIt measurement then slowly drag it until the number's right, but ... I should make an add-on or something. :-)
@@darrennew8211 Hmm... Maybe some maths in geonodes (you can also use maths in the scale box and just do the new size wanted divided by the original size to get the ratio wanted.
@@ArtisansofVaul For sure there's ways around it. It just seems weird that you can use dimensions in move but not in scale. I should learn enough geonodes that I can make an operator to scale the bounding box of the selection to a certain absolute number. Way easier than Python, I think. :-) Thanks for the idea! I don't use geonodes nearly enough.
If I understood right 1 blender unit = 1m. For most 3d printing slicers 1 unit = 1mm. So it's like you are modelling in mm there. But, what if in your head this gear is for a bigger machine? It would get misinterpreted by the slicer. I find it very odd we can't set in blander how much a default unit is (instead of adjusting the unit's scale in the properties panel). Telling blender 1 BU = 1 cm, let's say, would make setting up the scene scale much more practical. Also, adjusting the scale in the properties panel messes with sliders sensitivity and other interface and default settings.
@brunoosti1 I mean I generally work around that size so 10BU = 1cm isn't particularly hard to work at. If you really need to you can change the scale but I avoid it. The other option is as you export the object/STL if you bring it into 3D builder you can set what the 1BU is at that point (for example cm).
@@ArtisansofVaul further researching the subject, it seams only a few formats carry the units system with them, also. So what matters most seems to be what each software addresses as "1". I like to keep everything default in blender (not to mess with the UI) and change the metric units to display as mm.. from there, rescale in the exporter... meh.
Thanks for the video, but bro, fix the microphone, you have an overload in the sound, turn down the sensitivity of the microphone and add volume in the sound to compensate
@feelingblue6036 I'll have a look. My speakers were playing up when I was editing a video recently (can't remember if it was this one) so that may have messed up my settings when I was listening to the sound as I edited. Not sure if my other videos are the same for you...
Letting me know clean topo is not absolutely necessary for 3D printing is the tip that made this vid worthwhile to me. Thanks : }

Brilliantly useful. As you know your lessons have already helped me make many useful things!

@@unknownBoy85lover 😁My pleasure. It seemed a fun short project to document.
@@ArtisansofVaul that was whole fun and a lot of things to learn for me thanks my friend 🙏🌹
Interesting as always, especially since I am considering getting a 3D Printer! What does that printer cost and where do I get one?
