    You could, but depending on how you’re fixturing and how big your piece is, that can be really difficult. It would only really be okay with small pieces fixtures close to the open ends.

    Also, for a vacuum system has to have a hose coming down from above to avoid snags.

    Dude! I was born in the wrong decade- Shopbot at high school! The space for the Shapeoko is about 46”x 60” I think, would have to measure it again. If you need help resizing let me know.

    Nice bench! This particular design is too complex for a dimensioned layout, but you can print the PDF layouts at full scale at any print shop that does large format printing and use the technique I describe in this Instructable: https://www.instructables.com/id/Digital-Fabricati...All you need is a drill and a jigsaw.

    Yea, I used a laser cutter for the llenses. If you don't have access to one you could use the PDF template and score the outline with a hobby knife, then score and break straight lines around the curves and grind down what's left with a file until you get a smooth curve (that's how it's done with stained glass , for example.

    I just did the math, and I think I could sell kits for around $250. The print alone is 40 hours with almost a whole spool of filament (about $30); the laser cutting is pretty quick but the acrylic is about another $4; the monocular is $15; the hardware comes out to about $3; the strap, foam, and rivets are another $2. Materials come to about $54, machine time comes to about $34, and there's about 4 hours of labor involved if I'm being generous. If you or anyone you know is still interested, please give me a shout and I'll set up a product on my online store and post a link here.

    awesome! Looks spot-on to me. You could make a quick Instructable (just one lesson) and link to that here, that way you could add stls, the fusion file, images, and any process info you might have.

    Definitely. I've cut down all my firewood so it's too small to tumble out, but that's extra work that could be avoided with a screen.

    I see where you'd going with this. I think you'd still need some kind of a break though, unless you with with only right-angles.

    There's no shortage of Instructables projects you can do with $20 and some cheap tools. I've made lots of projects that fit that description. I've also made a comprehensive guide to making complex projects like this with some cheap hand tools and a large format print from Kinko's, which I've linked to in this instructable. Don't think i'm unaware of how incredibly fortunate I am to have access to a shop like this. At the same time, don't think I never had to struggle and bang out ramshackle projects with no money and no shop at my disposal.

    Those are both really good ideas. I's also like to make a set of tools (shovel, poker, broom) that hang off the side or off of a stand.

    I haven't, but I've seen some awesome projects on Instructables using old propane tanks. There are also some really cool fire pits that use dryer drums.

    Good comments! You read my mind. I spent a good bit of time designing a mesh / grate /interlocking vertical planes solution for the embers. If you're interested I could post the files for a few versions. At the end of the day, I decided to just let the chips fall where they may. The fireplace is enclosed, and there's nowhere for the embers to go. There's a hole in the middle of the platform for water t drain out, but aside form that it's up to me to scoop out the ashes when the pile up.

    That's definitely a smart idea. If we were in an area that was prone to fires, I would most certainly make a chimney with a screen to catch embers.

    It's definitely free, you just have to choose a startup / hobbyist / educational license when the 30 day counter runs out. You can renew a startup / hobbyist license for free yearly, and you can renew a student license for free every three years.

    My guess is that you'd have to have a very high wind load to knock it over. If you keep the proportions the same, I'd imagine the weight of it would keep it steady. Closed polygons like this are incredibly stable as long as they're bottom-heavy. If you were worried about it, you could always pour some concrete ballast into the legs.

    Yeah, for sure. I was thinking a good edit would be to make the trough at the back a snap-on insert, that way you could change it out for an iPad charger like you said. It would be a fairly easy thing to do in Fusion, are you familiar with the program at all?

    Print the PDF files provided in step 2 at any print shop that will do large format printing (Kinko's in the US will do it). Print the sheets on 48" X 48" paper at 100% scale and they will be the correct size. If they can't do exactly 48" X 48", any sheet size that's bigger than that will work as long as they print the PDF files at 100% scale.

    Thanks! To get it into Fusion you have to "upload" it. Open the Data Panel (grid on the upper left corner), double-click on a project, then click the "upload" button. That will bring the file in. Everything in Fusion is on the cloud which is why you have to upload it instead of just opening it natively.In terms of orientation, I printed everything basically upright, if you get my meaning. That seems to be the best way to get a good result. Have a look at the screenshots:

    Thanks man! Yeah, I've had a lot of practice. My desk is so serene now...

    That could be really cool. You could also paint them- Montana makes some really awesome colors.

    Lesson 3: Drawing in 2D

    This is a good start- you've got the proportions pretty much right. A few things will help: 1. Use the straight line methods I demonstrate in Lesson 2. The sketchy lines you're using here (short strokes) are really making the drawing fuzzy. 2. Use construction lines for EVERYTHING. You can never have too many. Do them in pencil, then do the rest of the drawing in pen, then you can erase the construction lines if you want to. They help a lot with keeping the lines straight and true.

    The only way to fix that is, you guessed it, practice! It takes a lot of repetition. A good way to make the practice manageable is to just draw straight lines for about 5 minutes before you draw something.

    Well done, man. That's a really clever way to get a hole in the center of the tops- most people don't know you can do that with metal calipers.The bevel on the hole really improves the aesthetic, but if you don't have a table router you could get a result that's just as functional.I know enclosures for speakers of this size usually have a hole to avoid suction when the speaker moves- did you have any problems with rattling or bad fidelity?

    Lots of markers bleed like that. Usually people just put a scrap sheet behind the one they're drawing on. This looks good. Keep practicing straight construction lines and you'll get better results.

    Yeah, parallel lines only come with practice. There's no way you'll be able to do it right on the first try. A lot of designers warm up with parallel lines for a few minutes every time they start drawing.

    This looks really good, but remember that you're much more likely to get accurate measurements and really be able to study the object if you do a multi-view projection like the one demonstrated in this lesson. The drawing you've got here is more a presentation drawing, but remember that this is a really useful way to work out an idea before you're ready to present it.

    Not bad. Keep practicing getting the construction lines parallel. If you spend some time on that in the beginning, you'll get much more accurate drawings. A stitch in time saves nine!

    Yep, ellipses are super tricky. As you can see, it helps to draw the cage. This looks really good except for the ends being a bit sharp.

    That looks pretty good- clean lines and a good level of detail. It looks like the vertical lines aren't parallel though, the ones to the right look slanted in relation the ones on the left. The horizontal ones look correct.

    That's a good subject. The best way to improve with this skill is to practice drawing construction lines, trying to get them straight and parallel. If you get that right before you start adding detail, you'll get much better results.
