This is a dispenser from the popular online free to play game - TF2. I may be adding some tools and ammo to go in the draw at the bottom as in the game. In the downloads there are the STL parts, the sketchup source file and a pre-made zip of all of the STLs. Enjoy erectin' your dispensarrs! NOTICE: The original concept for this model, the Team Fortress 2 - Dispenser, is copyright of Valve Software Incorporated 2012.I have not yet tested the model and might not get to it this year even. I can see that "Gas Bottle Pipe" and "Gas Clip" will need supports, the gas clip less so. There is a gap of about 0.3mm between parts that need to slot into each other. I think that will be an adequate amount for mine, maybe a little too much for other printers. Please use the dispenser.skp for assembly. It has the model with all parts both laid out and assembled. Happy building!
