[Swansea Hackspace] 40W CO2 Laser

[Emyr Morris]

I was thinking that jobs would probably be in the order of mins. So yes, £5
sounds reasonable to me.

Unless I don't have much change on me I always chuck a minimum of a quid
into the pot for suing the 3d printer.

I am sure everybody else must do the same.

You won't get a beer for less than £3 in most places now, a quid for just
over 10 mins fun on a laser cutter would be a bargain!
