Our MakerBot Replicator Dual needed some help. One of the extruders was clogged. It was the type of clog that could only be fixed by partial disassembly. It seems to be pretty happy now but the filament loading sequence seemed to produce an extrusion that periodically sounded like it was slipping. This test print seems to have worked out fine, so we’ll just keep an eye on it.
Bluetooth hardware with pins added
A BlueSmirf is a bluetooth modem that can be integrated in to Arduino based systems. I’ve added some pins that I’ve bent to allow the card to be positioned vertically from a breadboard for easy test and hopefully better range. The bent pins will likely work well if we plan to integrate it in to a headband or other wearable project later on.
So… I finally got around to trying it out. The scallop that I scanned some time ago and have 3D printed in ABS plastic and CNC carved in wood now has been done in clay. I used a chunk of “bone” dry clay and a two stage router bit series. I’m pretty happy with it for a first go round and still have to trim and fire it.

Trimmed the excess before firing.
This video shows the router on it’s second finishing pass with a finer bit:
This video gives you an idea of how thick the block is/was:
During a week when the students were on break, I was thinking about what could be the largest usable item that we could 3D print? There are lots of models of motors, cars, and other junk for download on thingiverse.com but I was wondering if we could print a skateboard, a scooter, a bike!
I had all but forgot about the idea until recently when Shad had brought up something similar and then we started to brain storm about it and decided to see if we could at least start with making a scooter.
Here is version 0.2 of a wheel for the scooter. (3D printed in ABS, Fill 15%, Shells 2, Layer height 0.2mm)
