Printed Business Cards

I was recently embarrassed at a presentation that I gave when asked for my business card.  Sadly did not have one to give.  Well no more!  Here is my new card.  I used the z-stop function on my printer to force a filament change at 1mm.  This allows the base (natural filament) to be laid down then I change to black for the lettering.  So far, everyone that I show it to has loved it.  It is a bit of an expensive card.  It cost $0.175 of material and 22min of printing.  Definitely not a card that I can give out en masse and is more of a card to impress.  The semi-transparent natural filament allow the text to standout even more (but is hard to capture in a picture)

Filament Winder Progress

I finally made some progress on the filament winders I got the parts for a while ago.  So far I got the spool assembled:

Small Parts Bin

I keep my assortment of screws in one of these


But some of the part I have are too small.  They can slide under the plastic dividers.  I printed some small bin that slide down inside the dividers to hold the small parts.

They came out great.  If you want to print some too you can find it here:

Aluminum Arms

I alluded to the getting Bottleworks Aluminum z axis arms ( and now I have them and they are installed.

The install was NOT as simple as the heated build plate install.  The instruction for the arms calls for a complete disassembly of the z axis to remove the OEM arms.  This took the better part of 2 hours (possibly some interruptions in between) but it definitely a far cry from the 10 min install for the HBP.

I am very happy with the result.  The product is very professionally made and the instructions are easy to follow.  One unexpected result is that I am getting much more consistent sticking to the build plate.  I suspect that the OEM arms were slightly flexing when the filament was getting laid down and this is no longer happening.  Some minor adjustments to the height that I am leveling at allowed the parts to pull off more easily.

Once again hats off to Bottleworks for another great product.

Apple Disk 2 Emulator case

I have been commissioned by Koichi over at to make a case for his new disk 2 emulator board.  He was nice enough to send me on of his boards for reference.  One thing I did not realize is that it was going to be so small.

Thanks to my friend Alex and his fellow Apple collector Geoffery for acquiring an original that I can digitize to try to get the features of the case.  I started by trying 123D Catch and I think I am going to need more work on getting it right.  It is also possible that I may have to abandon this approach and go back to the old measure and draw.

Stay tuned for updates on my progress on digitizing this classic.
