Marvin the Monitor

Last night I wanted to test out tweaking my layer height on my 3D printer. I picked the Marvin Keychain from Thingiverse since it was small and had some details I thought would be a good test. He can hang out on top of my printer and monitor the following jobs as they are run.

As you can see in the image below, I’ve set the layer height to 0.15mm and also increased the speed to 125mm/s.

Overall I was happy with the test. I have some sanding and cleanup to do on the print, and I can also use the print as a test on finishing and painting. If you consider how zoomed in that photo is (it’s a very small model) it didn’t turn out too bad. I do wonder if printing at a slower speed would melt the layers together a bit more, though.

Coffee Cap

More 3D printing tonight!

This time, a screw top for our ground coffee. This clever top pieces together on top of an existing bag of beans (ground or whole) to make sealing and pouring much easier.

I tried printing this one with a 0.15mm layer height. I have to sand down a few pieces since they’re pretty tight, but when trying to seal coffee that’s a good thing! If you check out the Thingiverse project you’ll notice there is also another cap that can be used for pouring; I may have to add that next.

Apple Lightning Cable Protector

While I’m much happier with the durability (and ease of pluggable use) of Apple’s Lightning cable, I’ve noticed that all my cords have started to disintegrate. Electrical tape seems to extend the life, but doesn’t feel very solid and looks gross especially after gunk starts accumulating on the cord end.

Apparently I’m not the only one since I found this model on Thingiverse to print your own protector.

It’s a relatively quick print at 28 minutes. My main advice is to be sure to add a brim around the edge on this model since it is so skinny at the base. My first print attempt broke free from the glass plate as the leverage applied to it grew the taller the object became.
