It’s going to be a big weekend for everyone attending Maker Faire Bay Area. Here are a few quick ideas for what you could make to be fully prepared for the festivities.

Business Card Holder with Top by eM5

I saw one of these on Annelise’s desk the other day, and I have to have one. If you get a card from me at MakerFaire, it’ll be from one of these suckers!

But here’s why you should have one for MakerFaire. Trading cards! Shawn  Wallace at Make Magazine has designed these awesome 3D printer trading cards for this weekend. There’s no word on whether there will be actual cards – looks like these are just designs right now – but in case some enterprising person turns these into cards, you’ll be prepared with your card holder!

Mustache and Monocle by chefmaki

Disguise!

Are you supposed to come into the office on Saturday, but you’re planning to sneak over to Maker Faire instead? You need this Mustache and Monocle by chefmaki, just in case your boss shows up. Also, if I see you walking around Maker Faire with this thing, I will feature you on the blog, no questions asked.

Whistle by madkite

A Whistle, either this one by Zaggo, or this slightly modified one above by madkite. If you’re bringing your kids to Maker Faire, and if they have a tendency to run off, you can use your whistle to get their attention. Or perhaps you can use it to referee some robot basketball. These are just ideas; a whistle is always useful.

Nepenthesis by Ecken

A beautiful Nepentheses Planter by Ecken. One thing I want to do at Maker Faire if I get the chance is visit some of the gardening booths. I like the idea of making these Guerilla Garden bombs full of wildflower seeds and throwing them around my neighborhood. Maybe you could leave the planter at home, but it would be a great home for some of the flora you might pick up over the weekend.

Trebuchet by jam4ar

Trebuchet

When does one need a reason to make a trebuchet? Make this and launch things; at Maker Faire. Case closed. Here’s one from jam4ar.

Anyone who has ever used Apple earbuds knows that they look nice and feel terrible. Honestly it seems like those earbuds are made for robots. I’m going to go test a pair on R. Maker in a minute.

If you’re not a robot, Thingiverse user and industrial designer J.C. Karich has solved this problem very elegantly. An adapter for Apple earbuds to work as over-ear headphones.

There are two awesome things here.

1. If you want to use your in-ear headphones, you still can. There’s nothing permanent here.

2. Because you’re making these on your MakerBot, you can adjust the strap around your head to be the exact right size by printing more or fewer parts. Or, I suspect, since the curve of each section is constant, you could slice one piece at any point, as long as the angle of your cut is right.

This is a Work-in-Progress on Thingiverse, but here’s more of J.C. Karich’s work. I particularly like the G.I.P.S., a 3D-printed global positioning system which gives you an indirect path toward your destination based on different kinds of “intuition”. A perfect tool for the wanderer, and it looks like a rock that you might pick up on a stroll through the woods.

On his blog my plastic future, Gregg Wygonik lays out why Bonzai 3D (B3D) is a good tool for modeling for your MakerBot, and maybe better than SketchUp Pro. Gregg says he wanted to find an alternative, in case SketchUp goes through some changes after Trimble takes it over from Google.

Sketch Up Pro and B3D run about the same in terms of price (just under $500 for both). However, he says his files from SketchUp occasionally have some problems when you try to slice them in ReplicatorG. No such problems in B3D:

Half the time I would have to rework parts I made in SketchUp that had holes or other simple design bits due to errors with slicing in RepG; no such issue with the many things I threw at it from B3D. Interestingly B3D has the ability to “diagnose” various potential problems when you export a STL file, but even with it reporting issues with a few of my objects, I had no problems with slicing/printing.

Here’s Gregg’s Pro/Con list for Bonzai 3D.

Things I liked:

• ability to draw lines and primitives as walls (think: no need to draw an extruded hexagon followed by another one a little smaller and push/pull to remove the middle, just draw an extruded hexagon with a set wall size and done!);
• some pretty sweet additions to regular booleans (slicing, object and surface splitting);
• NURBS with some really cool blending tools, in a much more approachable interface than Blender;
• 4-up “old school” view (top, left, right, perspective all at once);
• helix creation (screw tops!!);
• rounded or faceted edges with myriad settings;
• right-click on any tool and set a keyboard shortcut;
• and my new favorite: thicken, which takes any non-solid and turns it into a solid of a specified width

Things I didn’t like:

• some features require the setting of custom workplanes while some don’t and you don’t know until it throws an error dialog (workplanes are all new to me, but I like overall);
• inconsistent workplane handling (“lock workplane” sometimes doesn’t lock, and you have to use “save custom workplane”);
• adding dimensions to a part is hit-or-miss whether or not it will measure between the points you click or the entire edge you’re touching, while “measure distance” works perfect but doesn’t leave the dimensions on screen;
• too much reliance on hovering to open up tool groups and additional options (small gripe)

TheNewHobbyist's Man Cave, the home of Thing-O-Matic #3804

If you enjoyed that delightful scone cutter video a little while back from TheNewHobbyist, whose work we’ve also featured here, here, here, and here, perhaps you’d like to see where this Thingiverse genius does his work. Looks like a happy home for a MakerBot, and this picture really gives a feel for the room. Chris seems to MakerBot by lamplight.

I’ll share these in the mornings now (that’s New York Time!), just as long as you all keep sharing them with me.
