Summary

I know guitar picks are no new idea of something to print, and I should probably cite just about every pick already on Thingiverse.

However, I designed my own picks based on purchased pick I placed in a flatbed scanner and traced in AutoCAD. I like the feel/thickness/shape of these picks above any others I've tried.

I have included 2 files. On my printer with standard .3mm layer height these translate to 2 or 3 layer picks. 2 layer picks are my favorite although a harder pick is sometimes desired.

Print a bunch at a time! They are less than 15 cents apiece to make your own in cool colors.

thanks for the reply. As soon as I submitted the question I realized that I probably didn't need the raft and it's working fine. I'm experimenting with the thickness for bass picking. Thanks again! What are you using for the heat element/bed? I just got a M3D with a small (128x128mm) print bed and there don't seem to be many options for something so small.

I do most of my small prints on a PrintrBot simple, the 4"x4"x4" one. Doesn't come with a heated bed, and I didn't like the heated bed kits they make out there...

Decided to screw an auxillary bed made from 1/8" aluminum into the old bed with springs in between - gives me the ability to adjust the height. I cut a groove in the bottom of the bed (on the table saw!) and used orange silicone RTV to glue a thermistor under roughly the center. Then I used the RTV silicone to glue a 120V silicone-rubber heater on the bottom of the bed. The heater power is switched through a solid-state relay based on the switched 12VDC output on the PrintrBoard (PrintrBot's controller).

I'm thinking of sketching it up on autocad and posting it as a project on here with good pictures, to help others out with the mod. Will shoot you a link if/when I do!

How hot does the heater get, or need to be?

For PLA I have mine set to print first layer at 60C bed and then drop down to 50C bed for the rest of the layers.
ABS, I've had good luck printing 90C bed throughout the print.
Searching around it looks like people are setting their bed temps as high as 120C for ABS. My custom setup has gotten over 100C pretty easily, need to top-end test it sometime!
You can always reach higher temps or get to temp faster by adding wattage on a heater. Lots of 12VDC heaters can't push the wattage required to get up to temp. Plus since the printrboard can't support the amperage required to heat directly off the DC output anyway, might as well go with a 120V (or 240V, european) model.

Thank you for sharing. I'm very new to 3dp and I can't seem to be able to print the picks in a way that allows me to separate them from the raft (using M3D printer/1.75 mm PLA). When I am able to get a wedge in between the layers to pry them apart I end up pulling off one of the surfaces. Any advice is appreciated.

I have a heated aluminum plate as my print bed, and with masking tape down it will stick fine, no curling, without a raft. If you have a flat, solid (non-mesh style) print bed, even without being heated you may be able to get away without a raft. Make sure to allow the picks & the bed to cool before trying to remove them! Best of luck

If you dont mind me asking what did you use to make these was it like a 3d scanner auto desk inventor google sketch up ??

I started by scanning a commercial pick on a flatbed scanner, importing the .jpg into AutoCAD and tracing a few hundred points around it. Then I turned it into a spline and changed the shape a bit. Once I had a finished outline I copy/pasted that into Inventor Pro and extruded it to its final thickness, and exported it as an .stl.

The only reason I'm using AutoCAD and Inventor is that I learned them in college and still have my student versions installed. SketchUp would work just as well!

Im going to make some and sell them
If thats ok with you
Great Design

Go for it! With a $50 spool of PLA from Deltamaker it works out to cost ~13 cents apiece. With the $30 stuff from MakerGeeks it ends up being ~8 cents apiece. Cheap enough to sell at a nice margin!

Good luck!

is that the 1kg spool ?

You can pick up 1kg of hatch box for $15 on amazon thata where i got mine and it is very high quality

I've heard mixed reviews about cheaper filaments, which is why I usually buy from MakerGeeks. Just bought a $15 roll of filament on ebay though that I'm waiting for... should be interesting to try!

This is not cheaply made the spool is very solid and i usually dont even have to use glue on the bed to make the filament stick my friend recommended them to me he made his own 3d printer from scratch no kit at all he has been in a couple magazines but i use it when i print objects with multiple parts but i use a cheap filament for the picks because it is the same layer over and over so it has more support and comes out fine but the cheap filament isn't good for printing complex things

How long do these last ???

I haven't had one bend, fray, or wear out yet, but they do shred pretty well!
