Slowly slowly catchy monkey, you'll win I know it, especially if you show those remaining tants what's in store if the misbehave by way making examples out of the others with a club hammer
In other news:-
Knobs have arrived look OK, have a slight texture to them, had a go over with a piece if fine wet and dry. Also they are loose on the shafts but is easily fixed with a small square of sellotape pushed onto the end of the shaft before pressing the knob on.
Colour is never going to a perfect match but I think this colour is as near as my print depot could get and it's called light stone. No doubt once its been used a few times it will begin to get a bit darker with finger grease etc.
Just noticed that there is a slight colour variation on the other knobs anyway.
EDIT:
For anyone interested in getting some 3D printing done here is the address of the printer direct as promised
Print3d@techie.com and this is more suitable to people in the South East of the UK but postage would not be a problem but I could imagine that long distance printing / communication / checking samples could get a bit fraught with distance but its your choice if you don't either have a 3d printer or know anyone willing to do some for you.
