Parts that fit odd shaped objects - 3D design for 3D printing pt4

after a photo model most of stuff can be done in blender tho, whats purpose of this then

There has to be a better way to use a reference photo than all of this messing around with arbitrary lines and eyeballing. It can't be such that a program like this doesn't have a robust way to use a reference photo, can it?

can you explain why the specific goal of no supports? for some situations if it isn’t possible to work around it would be good to understand the impacts.

Cracking vid Michael. I've used Onshape for a good while, but never used the reference photo technique; that's definitely in my toolbox now. I also need to get up to speed on keyboard shortcuts.

Love this. I'm new to the 3d printing world. These videos r brilliant.

On a shape like that it can be better to take an imprint of the cavity using various techniques like plasticine on card or a rubbing.

Adjust CAD dimension would be the best if you want to share the model with everyone

You da man! 🤘

Excellent tutorial on prototyping. Thank you.

Love this series. I’ve been using Fusion for years but really impressed with OnShape because of this.

You should use a high power led like 1W with aluminum PCB theses small led doesn't last very long and aren't powerful at all!
Why using 3 li-ion battery? You don't need 24h run time one is more than enough as long as you can replace it easily (with this solution you don't need a charger on the base)
And it's much more lightweight so you don't need strong magnets

I print engineering prototypes, useful mechanical parts I create to solve daily problems as shown in this video, and products that I sell. This was a GREAT video. It's a very good example of how OnShape is used as a fairly easy and intuitive but full featured 3D CAD tool. I recently bought a 4WD Hijet Japanese mini truck and I'm slowly remaking it in 3D printed parts. Tonight - a rubbery TPU mounting adapter for a universal replacement fuel pump.

Just getting into 3D printing, and this is exactly what I'm looking for. I am also an instructor, and recognize your well honed teaching skills, you are very good at it. Thank you for this series, and will be referencing them as I move through the many projects I have on my to do list Thank you again!!!😁

This was a great project! Thanks for that!

nice video but I have a question. If you have to print something which should fit onto another object. Like your vacuum on the model. Whats the measurement you in- or decreased that it fits perfectly? 0.2 mm?

Pro Tip: You can also print your model on a sheet of paper with a regular printer to verify the dimensions this is a gamechanger with big prints

Just trace the shape onto some graph paper 🤦‍♂️

Onshape looks great but I can’t use it at all. The internet where I live just keeps failing so an in-browser application is useless. Is there anything for makers who need a local solution on their desktop pc?

Very good tutorial 👍🏻 The only thing I would add is to make sure you keep the camera leveled with the surface you are making the piece for, otherwise it would be skewed. Thanks for sharing 👍🏼

mindblown with the picture as reference.

Great videos, just so befitting for beginners, containing some complexity, but not too much🥰

I really love your channel and your videos.

This is exactly what I was looking for. Being new to the 3d printing world this information is vital for my projects, thank you. I am gladly going to watch more

Please drill third hole on opposite side, it drives me crazy.

Have they removed insert image? I don’t have it anywhere

Brill! 👍😁🏴󠁧󠁢󠁷󠁬󠁳󠁿

This helped a lot but I'm still lost. I'm trying to model the parts of a 17rd magazine for the Sig P365 Xmacro. It's got a ton of tapers, curves, cutouts. Is there a good forum where I can get help understanding how to make this piece?

G'day Michael
I've been using Onshape for years, taught myself through trial and error. Only just stumbled on these videos and have learnt things I wish I knew earlier. Thanks!

This whole series is immensely valuable for getting my foot into the 3D world - Thanks for your effort!

You are too fast to explain the on shape features.

I could have sworn you talked about a camera lens in one of your video's that eliminates perspective. I have googled it for 15 minutes and can find it. Can't find it in your videos either as I scan through them. Any chance you know what I am talking about?

Great video as always. A clearance hole for an m4 bolt is never 4mm. A close hole is 4.3mm and a loose is 4.8mm.

Even when machining parts, this is true. The reason you can get away with using a 4mm drill bit is they wobble and create an oversized hole.

Just look up "clearance hole chart" on your internet browser of choice.

Keep up the great work!

In Freecad you select two points on the image. Then you enter the distace and youre done. Its a built in scaling dialog. Very handy.

Nice tutorial, and it works and adds something to the tutorial, however I don't think I would have made it like that. Having the tube to go into the saws hole has created a possible blockage in the direction of flow. Tapered to a point as it went into the hole, or left that bit off altogether and made the "D" shaped hole slightly bigger than needed, so there is nothing to restrict the flow.

I believe the reason 4.4mm was the sweet spot for the hole is because when using a 0.4mm nozzle the printer uses the exact centre of the nozzle as its referance and doesnt take into account the 0.2mm of filament on each side. As this is a circle, there is 0.2mm on the radius totaling to 0.4mm on the diameter.

Damn! I want to push the like button 100 times. This was great. Thank you for sharing.

I'm familiar with a few different CAD softwares, so I made an account while on my lunch break and learned the basics yesterday. You finally kicked me into having the confidence in making my own parts with this onshape series. Thank you.

I use Revit to design stl files. I know its not the best program to use but I use it at a daily base at work and make the hardest objects in a blink of an eye really acurate, and don't see the point of paing for other softwares

Second question, why didn't you just give the line for the bottom of the ruler a horizontal constraint instead of messing with trying to match angles? Or, why not give a parallel constraint to the two lines you drew? I'm still learning much of this so just trying to understand why you went with this method.

One thing you skipped over (apologies if it was covered before) was how you got the distance between the bolt holes. Did you just measure the distance of the outside points of the holes and the subtract the diameter of one hole to get the 28mm measurement?

This is EXACTLY the kind of bracket that I needed to design for the extendable legs on my drafting table (the ancient plastic ones have cracked and crumbled away). Currently printing my first prototype now. I'm so happy that I'm starting to understand how to make parametric dimensions that allow parts to be updated and modified as needed. Such a huge step in the journey of designing my own parts! Thanks so much for this series.

Onshape doesn't have a calibrate function!?

Have you used solid works before is on shape better

Great video as always 👍
