In 2016 I built Dr Ooze* with MCP (* it’s mine and it’s got an extruder, geddit?!?)
The aim was never to create a working 3D printer, I have enough of those I use at work. The aim was to create a test bed for learning all about 3D printers. The aim was to meet and solve every problem we could, so we didn’t even start with a kit, or even a complete plan.
The initial design was based on a Rostock mini, then upgraded, parts redesigned, calibrated, recalibrated and made to work.
It has a Megatronics mainboard, E3D hot end, and Repetier software. Delta printers are cool and futuristic - but they are an absolute nightmare to calibrate … we spent DAYS learning how to calibrate this printer!
With assembly help from my 3 year old daughter.
My nephew needed a new propeller blade for his lego. “Uncle Drew, can you print me one?” Of course I can. The original Lego design has only 2 blades. This one has 3 blades, so it’s definitely better ;) .
Here’s a quick video of some printing, you can see how the head dances, it is smooth and quick:
In 2020 during Covid lockdown, I returned to the project and upgraded to make Dr Ooze II.
