Anyone into 3D printing?

[glockman]

I'm still working on learning Tinkercad and having fun with it. Today I built a little piece that keys into itself around a 1.5" tube. The idea is having a nice, flat surface to make a straight line (around the tube) with a sharpie- which is the hardest thing ever if you've ever seen me try and mark a tube...

Is it dumb, yes? Do I like the idea of it? Also yes. Most importantly it helped me learn some stuff and things and I'll learn even more about tolerances and whatnot when I go to put it on a tube. Hopefully I can get the neighbor to print it for me.

Oh and I also designed a piece to fit over a Ryobi battery that holds a velcro strap in place. It has a little more detail underneath but it's still nothing that neat to look at. This one should be helpful for me. I actually designed it first today and then realized I could've done it way faster with some tips and tricks I learned later in the day lol

Not derailing at all. I have barely dipped my toe into the cad side, I'm pretty impressed with your learning curve.

You're not derailing. You are bringing up items to consider when printing and designing though. Supports on both models would be a consideration. could they be modified so instead of a 90 degree part that sticks out to something like a 45 degree that could be printed without supports?

He just printed the strap holder for me and sent a pic. I need to go grab it. I told him to just flip it on the “back” so it wouldn’t need supports. The texture on the top (and how fast it printed) makes me guess he did ludicrous speed but 🤷🏼‍♂️

For the supports on the other one, I figured I’d just print it with auto-supports on and see how it goes. I’m sure it’ll depend on filament and machine settings as well. I don’t plan on having him print that one anytime soon though, gotta prioritize my print requests for stuff I need lol

ABS is stanky....need to get some positive ventilation before I print much more of that stuff...

Yeah the neighbor’s Bambu printer (I want the same one) is enclosed and has a filter apparently.

 

[frieed]

My printer came with a filter but I have to source the activated charcoal for it and have not intalled it. The printer sits in a basement utility room so I decided to put the fan in a window to keep a low-level negative pressure in the room and not worry about charcoal. I can control the fan with the same G-code that would have run the filter fan.

Oh yeah I’m sure you’re fine

This guy is on a whole different level, holy cow. Learning some things too:

Print me one when you print yours.

I've always just used cheap blue painters tape to mark a line on tube. As long as you line both ends of the tape up with each other, it should be an accurate and straight line.🤷‍♂️ Your line guide would be quick and handy though. Maybe don't make it as long as the drawing shows so you can mark closer to bends or nodes...?

Print me one when you print yours.

I would, but in the end he pretty much said it was a waste of time, didn't work well enough for the hassle. But the build process was the cool part.

Check this out - would be easy to re-create for the common tube types you use. I'm super impressed with Brennan's idea and the cost is low enough to just buy from him. It's mostly just shipping cost.

Tuby Center Line Marking Block

A simple little tool that allows marking the centerline of tubing during the fabrication process. With some clever geometry this 3D printed block allows you to mark center of 1.0, 1.125, 1.25, 1.375, 1.50, 1.625, 1.75, and 2.00 tubing sizes using the two pen positions. Each position is marked...

Yeah that's one thing where I may just slice it in half. I really need to get a printer so I can just mess with this stuff and tinker. I'm thinking I may make one with common angles as well, we'll see. If I'm feeling really crazy I could do common tube notches too

At the very least I'll get more proficient at CAD which is cool with me

he said it caught like 60% of the shavings or something, right? I agree that's kinda meh. It was fun to watch him design it though

I've been trying out onshape for drawings. Pretty slick tool with lots of similarities to Fusion360.
I needed a stand to hold my tablet, kindle, and phone, so 15 min in onshape I started with this:

Which yielded this:



Which allowed me to print this:

OnShape is awesome. Basically a full featured CAD program like solidworks but web based and free.

 

[N-Smooth]

Umm that's amazing and I didn't know it was a thing. I've been wondering why Tinkercad doesn't have a function like that. I just got signed up and I'm messing with it now. Thanks for the tip!

 

[frieed]

The really cool feature about onshape and fusion360 is they are parametric solid modelers..
All of the dimensions on the sketch are constraints, not passive measurements.
I can go back to the initial sketch and change the spacing for the middle slot from 10 to 30mm and the model readjusts..



all I did was type in a new value for the middle spacing.

That was one of the first things I checked out because I had to widen that stupid battery strap I had the neighbor print yesterday. Widening it from the middle in Tinkercad without changing the distance between 2 inner pieces. So I had to cut the ends off and move them around until I got it right. Dumb. It’s cool to see the pros and cons of both programs though

It's a lot different from Tinkercad, that's for sure. I've been fighting with it quite a bit today. I did make a shape like @frieed and then moved it to Tinkercad. So that's a cool option for simpler stuff. It's better than building stuff with cubes I suppose 🤷‍♂️

They have tons of good tutorial videos.
