Summary

Beer Grenade or Beer Fire extinguisher

Instructions

Instructions:

Print the 3 STL files – I used 15% infill for the prototype, but more infill would be better.

I have also modified the Top part so the spring now works

Parts you need:

3D printer obviously for the 3 parts

M3 bolt and nut (I used M3 x 10 and plain M3 nut) all I had at the time – if anything the bolt could be a good 3mm shorter, so get your junior hacksaw out.

3.1 – 3.2mm drill bit just to clean out the holes – by hand you animals – not essential but would help (the model has 3.2mm printed holes)

M3 split pin (if you don’t have them lying about in your workshop like I did; go to your local garage – they are used lots to keep castle nut on suspension parts of cars)

Split ring or key ring – size not important but it must fit your split pin

Full or empty beer can – I prefer empty – good excuse to drink the contents

If you want the design to work – i.e. when you pull the pin the top / handle Knobs off – you will need a 3.5dia x 15mm spring – the one I used only just does the job so a higher spring rate would be better.

The 4 holes at the bottom are just in case you want tap out to M3 for grub screws so it fixes to the can (I haven’t done this on the prototype) but should work.

To the webmaster – sorry I have used photos of commercial products – I have no intention of promoting the products – but just let me know if you would like the logos photo shopped out and I will modify

The prototype was printed on an i3

If anyone wants the CAD files to make this much bettereeer just send me a message – I designed it in Inventor 2012 but I can convert to other formats if you want.

ME!!
