LIBRARY AS MAKERSPACE

Last weekend, I went to the annual Tee-Off mini golf event at the Brookline Public Library.  As a first time visitor, I was mini-golfing with my phone at the ready. Special thanks to the AMAZING librarian rockstar Robin Brenner for so many great ideas. It truly is worth a visit just to see her teen room. Here are a few 3D printing/marketing ideas to takeaway: Having a  3D printer filtration cart would be wonderful in our library.  Look at the price if you dare.  Right now I have to go downstairs to retrieve prints because we are concerned about the fumes and little hands touching anything while the printer is on.  I have a video camera set up downstairs using an iPad 2 and the free app called Presence  for monitoring but sometimes I do forget to keep checking the presence website while I'm on the desk especially since it makes this annoying beeping sound to say, "Are you still watching?!"..As the sign reveals on the cart, the propensity to want to lean or...

Since we have to worry about limiting hours of printing to when we are open learning to split items in Tinkercad is a very handy skill. I split this Disney castle that I found on Tinkercad for a student's Florida project. It was going to be over 10 hours so I split it in half so we didn't have to "print overnight". I tried to split this object in CURA first but no luck.  A little bit of superglue and this one will be ready to go. Just be sure that you don't adjust the size while in Cura because the halves won't sync up. 

This holiday season, I was inspired by snowflake silhouette 3D prints and wanted to teach a class using the draw-print image method I have blogged about previously . This time I would skip the drawing step and use google images to find a pre-made silhouette.   I started by googling Mario star silhouette. I saved the file as a JPG then converted to SVG using online-convert , imported into Tinkercad , then hit CTRL + D  multiple times for smart duplicate (thank you Tinkertips ). I tried once with mario stars and twice with the Doctor Who Tardis. Here are my results..  My conclusion was trying to teach a class in this is much too complicated for beginners. It required much more precision (as shown in the Mario star snowflake that broke apart because the stars weren't connected enough) as well as finding silhouettes that lend themselves to 3D printing. The Tardis was having issues because of design alone. By making the Tardis 20% fill, it wasn't enough for ...

This tutorial is a combination of the  DIY unicorn hoodie  tutorial I found on Pinterest and Adafruit's light up unicorn 3D print tutorial. I used some supplies from Adafruit's candle bows  that we made a few years back instead of buying new materials. You can buy the sewing conductive kit separately on Adafruit without the bows.  I won't go through every excruciating detail but here are some tips that they don't mention and a few workarounds that worked for me based on my supplies.  Supplies needed from both tutorials:  Hoodie (dress in my case) Yarn 3D printed Unicorn Horn with LED base 3D printer with clear PLA filament (I didn't use flexible as the tutorial calls for and it was fine) 1 LED (11mm tall X 7.91 mm wide) Conductive Thread Needle (small enough the fit through the battery holder brass side holes. In the Adafruit kit, I used the smallest needle on the right) Battery Holder Regular Thread Felt (not necessary bu...

Think of all the kits in your collection that may have been thrown away because the parts could not be replaced! I recently designed a replacement xylophone mallet for a circulating children's kit. Thanks to the digital caliper I was able to measure the dimensions from the old one on the right (was it chewed!? these mysteries bother me) and added some upgrades like a handle using premade shapes in Tinkercad  to the new one on the left. Since printing in PLA isn't as strong as the typical ABS plastic, I made a thicker bottom. This printed in 2 hours and took me 15 minutes to create in Tinkercad. Just another example of staff using the 3D printer in their daily lives! Speaking of which, Halloween is coming up so this year's costume was inspired by an Adafruit tutorial on lighting up a unicorn horn.    The library staff has decided to be storybook characters this year so it was right up my alley. The free horn, including a bottom to fit an LED and sew-able clips, t...

DEMCO, a huge retailer of all things library, released a makerspace section of their website that offers furniture solutions like makercarts, portable storage cabinets and even popular science kits like littleBits! For libraries having a tough time buying from outside vendors, this would be a viable solution, albiet a bit pricier than other vendors. Libraries usually have a DEMCO supply account especially if they have bought furniture in the last decade. I'm drooling over the 3D printer cart as we speak. Even if you couldn't afford DEMCO prices, maybe there is someone handy on staff that could DIY some of these furniture ideas onto stuff we already have. If I could buy anything in my dream makerspace, my top 3 would be: 3D printer cart , STEM cart , and some mini folding flip tables.    I'm really into everything being on wheels lately. Our library's makerspace isn't "dedicated" so the thought of having roving carts and tables that are easy to cart ar...

I can't take credit for this one. I subscribe to the Newton Free Library events calendar because they have lots of great examples of STEM programming and this one particularly struck me. This October they are virtually "carving" pumpkins in Tinkercad . Thanks John Walsh! The skills learned in Tinkercad for this project are holes, grouping, using multiple workplanes and rotating shapes. TIP: Make sure to leave plenty of room between the eyes and the mouth or it won't have enough solidity to print properly. I left 11mm distance between the end of the eyes and the beginning of the mouth.  Step 1: I imported a pumpkin shape from the web and added a sphere from the pre-made shapes on the left sidebar of Tinkercad. Step 2: I added a new workplane on the front center of the sphere (now orange grid appears). I used the roof for eyes and the round roof for the mouth out of the pre-made shapes. The shapes needed to be sized and rotated. Then grouped it all togeth...

I wanted to throw this one out there to the makerspace/Ultimaker community. Has anyone had experience printing food safe items? I just stumbled upon Cookie Caster , a free website to make your own cookie cutters and thought it would be a great program for the upcoming fall/winter holiday season. However, with some introductory research  from one of my co-workers, it seems like we might have to go with buying food safe filament.    Granted most of the plastic people use still has harmful chemicals like BPA even though it was FDA approved but that's a different rant for a different day. So the question is, if it is just a one time use cookie cutter, printed in regular PLA, with take some safety instructions, will it be OK? or should we venture food safe? Or should we just wait for more research......I think use-able bowls and cups are definitely out for the near future. On a fun food end note, our custodian is leaving who LOVES Cheez-Its so we're 3D printing him a b...

2nd attempt I have a glass water bottle that is very hard to clean because it has a small mouth opening. Normally I clean it with a paper towel attached to a chopstick. One of our staff found me cleaning it one day and said, "Why don't you 3D print something?" Why indeed! My idea was to take 2 toothbrushes, measure out the width and length of the bottom of the brushes with my trusty digital caliper, then make a long attachment so I can reach deep down without using my hand. I used pre-made shapes in tinkercad . My first attempt was a dud. It didn't fit inside the bottle! My second attempt with the entry holes very far down offered no support to the brushes and they just went willy nilly everywhere once I got inside the bottle. Now granted I could have taped them together or used elastics but this was not the point. all attempts So I figured, why not just use one toothbrush? The third attempt was a one hole design but the hole was too far down and the b...
