Notes:

21.19 m of filament, 172 grams, 45 hours 3min

Warp in corner of rail x-y motor segment. Build plate temp too low (?).
3.2 mm real hole measurement on lift couplers.

crappy photo album to be added

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.
