This is a journal for my attempt at fabricating a v3.0 Snappy on an Ultimaker 3 using Cura v3.2.1.

Feel free to add any commentary, criticisms, and advice.

TBH, the first part looks horrible.
Why does the printer print so slow, but is set to 250mm/s travel?

Yeah, I recycled the gears, and the motor support.

I print slow because the printers I use are at a makerspace on a large public university, and “maintained” by students. The number of times they have labeled underextruded and warped ass parts as successful is just obscene.

I thought the travel speed was how fast it goes when not extruding (I usually turn on filament retraction). Either way, that is the default setting for CPE on an Ultimaker 3 when using cura.
