Printing with trimmer line

As many of the shout box regulars have found out i have my printer up and running. when i finished it i had no material to print with and a massive desire to see my monstrosity work amd remembered something i had read online.People were experimenting with trimmer line (the stuff thats used in weed wackers/weed eaters etc...) but last i had looked into it deltas and bowdens were the new and most people were running 3mm filament. well after looking around i found .065 inch line which measures out to ~1.68mm.

the BoBs that never were

been a bit since ive posted anything besides talk in the shout box. now that my kossel is well on its way to completion and still seeing all these cool BoBs and variants out there. i figured i could put some of my old designs to use. i pulled up my old dropbox file and remembered all those projects i started. and thought i would share some of my insane designs. these are the BoBs that never made it off the computer screen. links are to dropbox folders cant embed from drop box (to my knowledge) and im too lazy to sort them and put them on photobucket!

BoB from toy to tool

i think its time to take my BoB from a toy to a tool. and i would like ideas from you wonderful folk at LMR.

what improvements would you all make to make BoB more classroom friendly?

what ideas do you have to help in the aid of manufacturing?

 

my basic guidlines are:

4xAA powered (most likely ni-cad or nimh)

MG90 servos (metal gears and kids seem to sound likea  good idea)

Arduino for a brain (not sure what board)

so please throw your ideas in to the pot and ill try and incorporate them into the design

assistance bitcoin mining

i currently took up bit coin mining to try and help fund my printer build and maybe even down the road help a production BoB become reality (i have not given up!) does anyone want to help my endevor? all it takes is a small (20mb) program and a worker name and password from me..if anyone is interested please let me know. it would be geatly appreciated.

3D printer motor group buy

so after some talk in the shout box someone posted these gems here https://www.sparkfun.com/products/10846 while they are a nice motor 17 plus shipping sucked so i went on a hunt what i was able to come up with was a contact to order direct from the manufacturer Wantai Motors they have no problems with a small order but the bigger the order the better the price gets. here is a link to the full spec sheet: http://www.wantmotor.com/ProductsView.asp?id=157&pid=80 for 12 units i was able to get the price down to 15.91 shipped here and thats only 12 units.

3D printed firearms(kind of)

first im sorry if this post is taboo and not allowed...feel free to remove it if so

 

first off i say "kind of" because a whole gun is not being printed. just the parts that are considered to be the actual gun.with all the reading lately and my interest in the subject i thought i would share what i have learned here in the blog.
