Prototype for poor man’s 3d printer pen. Unlike other more expensive alternatives, has variable extrusion flow control (not just one speed) through use of manual extrusion control mechanism (the trigger thingy).
Supports whatever material glue gun sticks are made of.
Patents not pending. Non functional prototype.
Probably is a functional prototype. Give it a try and show us what you make.
Do you sell kits? I’m not sure I want to spring for a fully assembled model.
Do you have a finer nozzle, I have heard finer nozzles are ultimate measure of quality.
Great, if wife sees this she’ll never understand why it is I need a bigger/better printer. Can’t imagine how much you’d raise if you put it on kickstarter 
3D printer pens from kickstarter is such a joke: 110% useless CRAP that makes people think they can do silly stuff they cannot IRL!
@Frits_Lyneborg Even if you aren’t too good at sketching / drawing in old-school 2-d / paper, and have no artistic tendencies at all, this “3d pen gun” will turn you into a pro! You will be able to make a perfect scaled 3d Eiffel Tower! It uses quantum i particles (imagination) to make anything you draw with it seem perfect!
NOTE: Does not include 4-D refrigerator for you to stick your kid’s 3d drawings on. Or a first aid kit required if you let your kid try to draw something with it and they grab the wrong end (ouch!).
@Jonathan_Foote Can I do an ugly, completely useless and fragile 3" version of the Eiffel Tower with this product after hours of frustration? Count me in, I’m backing you: This is worth every penny!!
HAHAHA exactly want I wanted to do when i saw those pens! Good job! Now you can sell it for a fortune!
