Hdd tray

Hdd tray: "

A parametric desing of a harddisk -tray for 3.5' harddisks. You can use it to design your own hdd-enclosures or hdd-racks. The air-holes are large and deep enough that you should be able to take the tray out without an additional grip You can use the holes in the bottom or the side to mount it. As you wish. If you feel like it, please add mounting-holes for a ventilator.

Lego crawler town

Lego crawler town: "

I don't think I've ever seen as unique a Lego creation as this 'eco punk' mobile town, created by Dave DeGobbi. (Click for a bigger pic!)

Crawler town roams the barren wastes of a post steam-punk world after cataclysmic climate change do to excessive coal use. Several such cities exist but Crawler town is the most popular due to the Aero 500 hydrogen fuel cell Air races that are held. Many people travel the wastes to Crawler town for vacation and to enjoy rare luxuries like Pizza, fresh vegetables and Beer. Travelling the wastes in search of minerals and aquifers ( vital for survival) the mobility of the city keeps it away from the vicious sand storms of the wastes.

Automatic post: Autonomous rover

Autonomous rover: "

Here is my answer to an realy good start if you want to create a Autonomous rover, built with an Arduino. projects is super easy:) 3d printing and build, mount the servo motor and wheels. youtube.com/watch?v=n2sAvA1jWBM and for next step for me. youtube.com/watch?v=5u52w2W6XrE

One Tool to make them all

Ein 3D-Drucker wie mein RepMan ist schon ein beeindruckendes und vielseitiges Werkzeug.
These: Es ist mächtig genug um jedes Werkzeug zu bauen oder alle signifikanten Teile der Maschine zu bauen welche benötigt wird um das jeweilige Werkzeug herzustellen.

Deshalb habe ich mal angefangen einen vollständigen Satz grundlegenden Werkzeuges auf Thingiverse anzulegen, den man sich ausdrucken kann:

Kleinwerkzeug

• Meine Schraubenschlüssel (parametrisch)
• ein anderer Schraubenschlüssel (von Masked Retriever)
  
• Meine verbesserte Version der Pinzetten
• Zirkel
• Trichter
• einfache Zange (hab ich noch vor zu verbessern)
  

Großwerkzeug

• Fräs-Arbeitskopf für BitsFromBytes RepMan (hier von Bogdan das ganze für den RepRap Mendel und hier ein anderer für den RepMan, und hier für den Makerbot CupCake)
• Platinen-Bestück Arbeitskopf
  
• XY-Koordinatentisch (bewusst unvollständig als Design-Wettbewerb)
• Schraubstock (parametrisch)
• Klemm-Halter für Dremel Workbench
• Drehbank
• An einer Tischbohrmaschine arbeite ich noch
  

Aufbewahrung: (nicht von mir)

• modular boxes
  
• Sortierboxen
  
• Kabelhalter
  
• Kabel-Wandhalter
  
• Werkzeughalter
  
• Haken
• Tisch-Haken
  
• Klemmen
• Dritte Hand
• Platinenhalter
• ...

UPDATE: I have moved this to the objects.reprap.org -wiki.

XY-table

Playing around with Alibre this sunday I though that maybe the design challence I opened (get 10 mendel parts for designing a printable xy-table) was too hard.
So I designed the basic frame myself:
http://www.thingiverse.com/thing:1831
Slowly I´m really getting up to speed on this amazing program.

With one small modification this should be easily printable but I deliberately left some things to be done. Just so as to still inspire people to finish the contest.

RepTap - self replicating plasma cutter

Ok, we all know the RepRap by now.
An open source 3d-printer that can print most of it´s own parts.

What I just heard was one giant step further:

A CNC PLASMA CUTTER.

heated print bed for RepMan

So here is my attempt at a heated printing-bed for the RepMan.

power:
I found these 37W heating-pads and a matching 120W power-supply
that I can manually regulate between 15V(62.5%) and 24V(100%).
I´m not using a temprature-probe to keep a target-temperature yet.

surface:
I´ll try to attach them to the underside of a copper-plate.
Experiments of other people have shoan ABS to still reasonably well to copper but very badly to aluminium.
If that does not stick I can always get KaptonTape for the surface.

mounting:
To isolate the plate against the temperature-sensitive polyacrylic-parts of the RepMan I´m going to use a ceramic wall tile like prusajr did here.
But I will not keep it in place using clamps but with screws, oversized, long holes for these screws and large washers.


thermal expansion:
That should allow the copper to expand in XY-direction so it does not expant too much in z direction while not interfering with the cross-supports of the RepMan during movement around the z-axis.

Die Maschine die sich selbst repariert

Wie viele Maschinen gibt es wohl da draußen die den größten Teil
ihrer eigenen Ersatzteile bauen können?
Und wie oft sind dann die Ersatzteile noch besser als die vorherigen
Baugruppen?

Nie unbeaufsichtigt lassen

Heute habe ich nach etlichen erfolgreichen Drucken wärend ich am anderen Ende des Zimmers gearbeitet habe den 3D-Drucker mal unbeaufsichtigt drucken lassen....schlechte Idee.



Glücklicherweise hat sich der Plastik-Draht verfangen und das Schlimmste verhindert.
