This is really a very cool design, and just looking at the PT I imagine it could be a pretty badass blaster with a proper barrel.
However, if you have the time, I'd like to ask a few more questions about the actual printout. I understand if you can't answer some of these questions because of your business model, but I'm gonna ask them anyway:
-What size filament did you use for this print?
-What do you estimate your printer's resolution to be, for this print?
-Did this print require alot of support material?
-What software are you using for slicing and g-code generation?
-If you are using Skeinforge, what settings did you use?
And then a couple purely nerd-driven questions about the Fablicator:
-How are you driving the axes on your printer? Steppers and lead screws? Linear actuators?
-How much power does it consume?
-How often do you have to change that cool borosilicate build bed?
-Is the build platform heated?
-The printer uses 1.75mm filament.
-The 'resolution'for this print is .25mm layer height, .4mm extrusion width.
-This print required a moderate amount of support, but only for the curves on the exterior of the case. Anything less than a 45deg angle does not require support. I could have designed it so no support was necessary, but it would make the blaster far less comfortable to hold.
-I used skeinforge, Pronterface, Marlin for the tool-chain that made the blaster in the photo, but are moving to kisslicer/pronterface/marlin as it is way faster.
-Oh god, there are too many skeinforge settings to list. If you really want to know I'll pm you my config file. There is nothing particularly unique about it.
-Axes are driven by Nema 17 stepper motors with 1/4in mxl belts.
-The printer uses about 400W. Most of that is to heat the bed.
-The bed never needs to be changed unless you drop something on it....
-The build platform is heated to 110C for ABS and 70C for PLA. It can get hotter, but we limit it because at higher temps the ABS can actually stick so well the bed will chip when you try to get it off.
