3d printed papilio pro cases

Recommended Posts

Nice one thanks! Perhaps add a photo of the finished thing to the thingiverse listing? I am loving openscad more every day.....

Good idea. I printed both parts and installed so will take pics when I get back in.

 

Ok, I added real pics to the thingiverse part. Here's one of them:

That looks nice Doug,

 

Any idea what it costs to make this sort of case? The last time I checked it was pretty expensive if you don't have your own 3D printer, has that changed at all?

No I don't Jack but I can see what numbers pop up for quotes at places like Shapeways.  Is that how you determined pricing the last time?

BTW, I built my Mini Kossel about 1.5 years ago at a cost of under $400. It can probably be done today closer to $300 but one would have to consider their time as 'free'.

Yes, I think I quoted at shapeways and it was something like $40 which is pretty high. So are you pretty happy with your Mini Kossel? The results look pretty good, do you have to do a lot of babysitting it while it prints?

Very happy with it. At one time I was doing a 2 day workshop on 3D printers and students built the Mini Kossel on day one and then we went over the software on day two. I did some pre-assembly so maybe 2 days for the build with an instructor. I take my MK to meetups and the FabLab(fablabsd.org) maybe 4 times per month and have not needed to recalibrate for 3 months.  The calibration process is the only thing which seems to put people off but Jack, you would _not_ have a problem.

 

The benefits of the Mini Kossel and specifically the Delta design compared to the Cartesian design is over 30% fewer parts, 3 identical motion control and structural segments and a light weight printing head(effector) so printing at 80mm/s is common with some going well over 100mm/s. This means faster prints. 

 

I can call and talk to you about it if you'd like. PM me if interested.

 

As for if I like the design as is I would say yes and no. I think I would eliminate the countersunken nut holes in the base and just size for M3 bolts to screw into the plastic. I'd like to make the top thicker by 1/2 the thickness of the .1" pin plastic separator and add the same thickness to the bottom of the base so an M3x16 screw could be used to hold them all together.  I'd also like to add 2 screw holes on opposite sides of the Papilio 16bit I/O Wing when mounted in Wing Slot B so a cover could be used over the Wing to protect it and the pins on it.

 

other then that I like it. :-)

I forgot to address you "babysitting" question. No, I did a good job calibrating it, insulating the hotend and dressing the wiring so I generally start the print and once it's on the 2nd layer I turn the 2nd fan(part cooling) and let it go. It's generally on the first layer that I see any issues needing addressing like not putting down new glue stick material(glue) so a corner or something comes up slightly. Very very seldom these days though since I have temp, cooling and speed well calibrated.

I'll get back on the case and add the extra thickness to the top(and/or bottom) for the 3mx16m screws, add some screw holes for a cover over the level shifter wing and code in a quick variable to create indents for the 4 screws so 3mx12m screws still work. Also remove the nut indents at the bottom.
