Waaay out of spec

Got several extruder jams today (breaking the print of my clandestine  world domination project , muahaha).
The filament should measure 3.0mm with, say, a 5% tolerance.
Turns out it measures 3.7mm at a length of 200mm.
This is premium PLA by a renowned supplier. I never had this with cheap PLA from China.
This sucks. What's your opinion?
 

PS: Remains to say, that the supplier replaced the material without a fuss. I got a brand new spool of material, which prints very nicely and is also perfectly up to spec.

Rolladenstopper (rolling shutter stop)

The stoppers on one of our rolling shutters broke this morning.
So, what's better to spend a rainy Sunday afternoon than designing and printing replacement parts to repair household items?

As usual, the sources are in the GIT repository and the part is published on Thingiverse.

A few impressions:
finished parts with mounting kit

look ma, I fixed it... ;-)

Bed: Mattress Frame Holder

I don't want the kids to get injured by the metal parts holding the bed frame, so I designed a plastic cap covering the bare metals parts that are mounted under the bed. Will print ten of them on the weekend. OpenSCAD files are in the repo.

Bed: Built

The bed is built – my kids are happy.
There's one more thing I need to do: adding some bumper around the metal brackets holding the mattress frame. There's a construction in the repo, it's currently printing.

last touches

happy "customers" ;-)

Good-looking Prusa parts!

Excellent bridges. Very small warp on two corners.

Loose screw

Extruder pulley set screew came loose = aborted print. Darn, this one's not mounted with Loctite. Fixed. Printing again...

Print, print, printing along ;)

Results looking good. Printing Prusa parts for 21st of April...

Strange patterns on first layer

I'm getting really funny patterns in solid fill on the first layer that is going onto the glass. Already played with temperature, up to no avail. Any ideas, anyone?


Printing again

Finally: I'm printing, after readjusting the belts and stepper driver current(!) of the Y an Z axis.

Printing Accident

I heard a loud crack after leaving my room for a short while.
Somehow the nozzle got stuck and pushed the glass off the print bed.
