[GreenKeys] Replacement Rubber Cap for Model 33/32 ASR "hammer"

[David Tumey]

The materials we can use in the 3D printer are fairly limited Wayne, I can have my engineer look into some alternatives - the stuff has to be extruded through a hot nozzle onto the platen.  

I will say that the PLA we use is pretty darn durable material, it is almost impossible to wreck the parts that we make here.

If you guys make a new rubber hammer you might consider making it out of black vinyl.  It seems to hold up well in the clear vinyl tubing replacement.

I don't know where to find a 3D scanner, but 3D printers are generally available in lots of places.  We have several "makerspace" or "hackerspace" places that are free collaboration/learn/build spots that all have 3D printers (and even laser cutters) available for free use.  There is even one library here that has set up a "make" section with a printer. 
 
So check your local area, and you might be able to use one near you. 
 
I would be interested in an STL file of that hammer, if someone generates one.  Or, with an original drawing, I think there is a local fellow who could help me generate one. 
 
Where do you source the rubber for the printer? 
 
thx,  gil

>>Recently my company purchased a 3D printer that we use in our product development lab.  We have been printing in ABS, but our senior engineer found an elastic material - black PLA - that prints a part that feels like 60-70 durometer Shore A - according to my calibrated fingers.

>>Typically we have our renderings done by an outside design firm in Solidworks then we upload the "STL" file to our printer and out pops our prototype part.  Unfortunately we do not have a license to Solidworks but I was thinking...if a list member could provide a drawing of the little rubber hammer "cap" that goes on the ASR-33/32, we could supply the STL file to the list and members could print their own parts on demand.  There is a printer from Cubify that is just at ~$1,000 - we paid over $50K for a machine with similar capabilities about 10 years ago.  I predict the prices of these things will be in the $250 range in 18 months so printing obsolete rubber parts for the Greenmachines might become routine.

>>If you or someone you know can provide a drawing of the rubber cap in Solidworks, I will print out 5 rubber caps for you on our machine in exchange and we can provide the STL files at no charge to Greenkey list members.

>>Please contact me off list to discuss any details by email.
