3D-printed prosthetic hands, social justice, and other 4th grade achievements with @DylanMRyder:

A little while ago, I shared the above video with the faculty. I wanted them to know we were much nearer the time when the 3D-printer would be a plug-and-play technology that didn’t require constant maintenance and attention. I also hoped to reinforce the awesome possibilities of 3D-printing and it’s impact on the world. (Remember how President Obama included a plug 3D printing in this year’s State of the Union address?)

Dylan Ryder and I were (at the time) trying to get our Makerbot Replicator2 to successfully and consistently work. I was antsy to finally print out some 6th grade math models, while Dylan and his students in the Maker Club were excited to build and assemble a robot hand. Dylan had been hoping to also initiate a prosthetic limb unit in 4th grade and bring the hand as an incentive. After watching the video I sent, Kate Berten, a 4th grade teacher here at The School at Columbia University, contacted Dylan about prototyping a social justice-inspired unit in the Spring about assistive technologies. As it turned out, the hand Dylan’s students were waiting to print was the same prosthetic hand that the kid in the video was wearing!

The installation of our new updated spring-loaded motor block has allowed us to finally build a Snap Together Robohand. Now, I just have to buy elastic string this afternoon in order to complete the working model…

Just upgraded our Replicator2 spring-loaded drive block with the help of these @Makerbot tutorials:

FedEx just delivered the Replicator 2 spring-loaded drive block replacement kit that I ordered from Makerbot earlier this week. It’s a free part, you just have to pay tax and any shipping/handling fees. Dylan Ryder and I just installed the new drive block and it works amazingly! It’s seriously like having a brand new and improved machine. If you haven’t already ordered the part, do it now!

Request the drive block replacement here: http://store.makerbot.com/extruder-upgrade
Follow the installation instructions in the video here:

The good people at Makerbot’s customer service also sent me this video about how to clear a thermal barrier tube block in the machine’s extruder with this video tutorial:
