3D Printing from pain to fun

After a long period of ups and downs and a relationship which best gets described as “complicated” with my Mendel Prusa i2 the results are really getting better and therefore also bigger. It also starts ti feel like fun to print stuff instead of beeing tensed up all the time.

So today I printed a fillament holder roll, which when assembled consists of two bearings and a plastic bearing holder (8*3*4cm). I also got in touch with blender to edit the STL files other than the non linux Sketchup, which lately tends to produce broken CAD models which cause slic3r to crash.

See the results below:

Howto use docker volumes containing remote sshfs mounts

For my audiobook-feeds github repository I needed docker to be able to use a host volume mount which contained a remote  sshfs mount located on my local raspberry pi with a attached external hard drive. For my own sake of documentation and to offer you something to profit from, I created this small howto:

First of all, connect to your server and mount your remote device via sshfs using the -o allow_root flag. The allow_other option I tried first didn’t work for some reason.

sudo sshfs paul@192.168.42.23:/my/remote/path/ /my/local/server/path/files/ -o allow_root,reconnect,default_permissions

Then run the container using the –privileged flag.

sudo docker run --privileged --rm -v `pwd`:/usr/src/myapp -w /usr/src/myapp -it --rm -p 127.0.0.1:8088:8080 --name audiobook-feeds audiobook-feeds go run feed.go

After that the root user of the container is able to list and to server the remote files.

I love podcasts.

I use them frequently and automatically downloaded by the Podcatcher BeyondPod onto my smartphone. In contrast to podcasts, I transfered my audiobooks to my smartphone by cable – which usually was very annoying. Therefore I wrote a little script that is able to close the gap by converting all my audiobooks into subscribable podcast feeds!

Of course it is open source and can be found here:  https://github.com/PaulPetring/audiobook-feeds

Some adittional facts:

  • it serves a website to browse your audiobooks and subscribe to certain books
  • serves rss and atom feeds for import
  • it offers a simple password protection to prevent copy right issues
  • runs in docker container (see MakeFile and DockerFile)
  • works when placed in subdirs example.com/audio/ (e.g. reg for ssl without wildcard)
  • allows custom theming and uses material design as default theme
  • handles encoding of filenames at best effort
default

I use it on regular basis and would like others to enjoy it as much as I do. So please feel free to use, spread and contribute to it. And see you soon 🙂

A case for the RepRap Prusa Mendel i2

Some time ago I built a case for the RepRap Prusa Mendel i2. We used birch wood and plexiglass. Combined with some Curves the final design is very transportable and nice looking.

Attached to some lights I found in the attic, the printer nicely shines in the dark:

Printing results increased significantly because of less environment influences – like wind or temperature changes which lead to warping and other issues.
