The Ultimate Catapult, almost. [Seej]
by roguemat, published
I present to you, The Ultimate Catapult, almost!
I originally made this to shoot the 2cm X 2cm calibration cubes, but it's actually the perfect Seej weapon too!
It catapults the cube an extremely impressive distance due to the angle that it releases it at.
It also has a fully working trigger system, and is sturdy enough to add quite a few elastics.
There are quite a few parts, but assembling it all is part of the fun, and totally worth it.
"almost" is because I have a few modifications (and yes, even MORE parts) that I have in mind for a V2.
Note: This is one of the first thing's I've made. I am very new to this whole printing thing, and even newer to modelling. I've just watched the Sketchup training vids on YT - so I hope the models are OK.
Please let me know if I've done things right. I've also included the SketchupFile so you guys can have your way with it. And a zip of everything.
It's rather complicated to explain the assembly, so please WATCH THIS VIDEO: http://www.youtube.com/watch?v=MjHKZ9OX4ec
Having only recently set-up my Thing-O-Matic, I printed everything with default Skeinforge settings, with one exception, I turned Extra Shells off. I printed all the parts between 10 and 20% infill, and although it looks like a mass to print, the final build is only +-27grams. Printed without raft or support, and needed to set the HBP to 110 to make some smaller things stick nicely.
I made this to print on my Thing-O-Matic, so it should fit on pretty much anything :P
Here's what you will need to print:
2 x SidePins
2 x TriggerPins
4 x PinTabs
1 x Bucket
2 x FrontBarTab (rotate this in ReplicatorG so it's flat.)
1 x FrontBar
2 x SidePanels
1 x TriggerBar
1 x TriggerTab
1 x TriggerBlock
I didn't record printing times, but as far as I rememeber most of the parts were very quick to print, with the exception of the side panels which took around an hour.
Have fun :D
