project of the week: bulbasaur planter

Ian

This week we worked on a 3D printed planter using a Bulbasuar model located on Thingiverse. The model looks great and printed really well in Colorfabb’s Bronzefill filament.

We ran into one large issue during the first few hours of printing; our Prusa i3 MK3’s filament detector wasn’t enabled so the print kept on going when our spool of fillament ran out! Unfortunately, we didn’t notice right away and the printer had no issues chugging along layer by layer sans fillament. Fortunately, we noticed the issue after only a few layers (approximately six) and were able to salvage the print. This was to be one of our longest prints to date, at almost 7 hours and we were already 1.5 hours in, so we debated whether we should cancel the job and start over. Once we added more filament the gap appeared only to be cosmetic and thus we pressed on!

There’s a bit of a gap there, Russ…

Once we removed the planter from the print bed, we did notice a bit of a wobble at the base. Although there was substantial infill before and after the gap, the missing perimeter wall left the model feeling slightly unstable. So, we decided to MacGyver it up and add a “bandaid”!

We measured the gap which was roughly 2mm in height, printed some narrow strips to use as bandaids, grabbed an old soldering iron tip, and then welded/melted the bandaids along the gap. Presto! The perimeter walls were reinforced and the whole model felt very substantial.

All we had to do from there was spend some time applying a bit of elbow grease to sand down the bandaid and remove some of the larger layer lines throughout the model. As you can see from the timelapse video below it turned out pretty well.

print all the things!

Ian

One of the best things about 3D printers is the opportunity to create anything you may need or want, whether it be completely practical and utilitarian or focused and specific to a particular project. Don’t have the bolt you need? Print it! Need a tripod riser to give you just the right angle? Print it! Lose or break a component? Print it!

Lately, we’ve been printing a lot of practical components such as:

  • dry-erase board marker cups (to replace the default tray)

  • 1/4-20 bolts (to mount our webcam to a tripod)

  • printer name badges (for our Prusa i3 MK3’s)

  • tool holders (for our MK3’s)

  • 20-20 roll-in t-nuts (to mount items to the y-axis on the MK3’s)

We also needed a door handle, so we printed that too. We went through a few design iterations, before we settled on the final version seen below.

In the spirit of all that printing we decided to design a printallthethings sticker. We will have the printallthethings sticker and our logo sticker on-hand when we open. Feel free to swing by and grab one!

project of the week: r/c fig #2

Ian

This week we continued building our r/c minifigure (affectionately named legü) by scaling out the head and printing the second hand. Scaling legü’s head required a quick reference of BrickLink’s minifig dimensions and watching a YouTube video by HBPankoke, to learn how to add the 2mm radius to the top and bottom faces.

This week we also experimented with timelapse footage per OctoPrint’s Octolapse plugin and 0.6mm print nozzles in place of the default 0.4mm nozzle. The timelapse footage didn’t work out at all, despite two attempts. Half-way through the first attempt the print job was accidentally cancelled and then during the second attempt the lighting was askew and made for some head-ache inducing glare! Live and learn… Next week we’ll experiment with a lightbar or perhaps an enclosure with a more directed light source.

Looks great! To bad this print job was cancelled…

Huzzah! Second time’s the charm.

The 0.6mm print nozzle made a huge difference reducing the overall print time by almost two and a half hours! Notice the estimated printing time below:

Tune-in next week to check on our progress, as we continue to build our life-size LEGO minifigure and try again to create a timelapse video of the print!

project of the week: r/c fig #1

Ian

Today, we began the first in a series of projects of the week. Each week we will feature something we are currently building creating at the makerspace. The complexity will vary week to week, but to begin we are tackling something big (or is it small?), as we attempt to build a life-size, remote controlled (r/c) LEGO minifigure!

Enhance!

Enhance!

While we certainly aren’t the first to pursue the idea of building a large LEGO minifigure, we will be putting our own “spin” on things and hope you will check in weekly to see the progress.

Inspiration for this project comes from a couple sources such as Adafruit’s Webcam Cover-up and XRobot’s Giant LEGO Skateboarder.


r/c fig: the process

  1. Research LEGO minifigures

  2. Design a 3D minifigure model

  3. Print relevant minifigure parts

  4. Assemble minifigure

  5. Add remote control (r/c) hardware components

  6. Program micro-controller

The process began this week with steps #1 and #2. We referenced a couple different minifigure models on Thingiverse and reviewed the dimensions of a standard minifigure. Then we built a model, using Adobe Fusion 360, and 3D printed one of the hands to verify the relative life-size’ness of our minifigure.

We are excited to share this project with you and hope you will join us next week to see our 3D printers in action, as we continue to print life-size LEGO minifigure parts.

Hello, Ridgewood! And hello, world!  We are very pleased to announce that TechAhoy, a non-profit makerspace is coming to Ridgewood, NY.  

We are in early stages of building out the space, so our journey has just begun.  If you are interested in being a part our new space please fill out our form so we can gather more information and best serve the community.

A makerspace is place where individuals can come together to learn, share, and build!

We plan on offering classes and programming in a variety of subjects, but we also want to be a staple providing you a place to show up and ask a million questions, tinker on your latest creation, design a 3D model, make a quick print of a prototype, design a video game, explore a new medium, take advantage of our soldering irons and hand-held tools, hunker down for hours with your head buried in code, or just take advantage of our free wifi.

We have completed our interior renovations and are presently adding the final touches to make the space a welcoming environment for everyone.  Please stay tuned, follow us on Twitter (@techahoynyc) and Instagram (@techahoynyc), or just check back here to see our progress!
