Ok I bought a glasshouse dismantled it and am in the process of reassembling it, but somehow the stupid gosh darned thing has moved off the level slightly, so i either need to re-dismantle it or put up with it, i have chosen to put up with it cause i'm lazy.

Anyway this means in a few place the glass panels don't fit correctly lengthwise, so I either have to

-trim the glass, which knowing my DIY skills will turn to custard,

OR

-increase the overlap between the sheets of glass

The second option is the most idiot proof option, however i can't find any overlap clips that are larger than 1cm in height

This is what an overlap clip looks like

The only thing even near to what i want is the below, but they don't ship to NZ anyway

https://www.amazon.com/50-Formed-Greenhouse-Overlap-Clips/dp/B009INGX4C/ref=sr_1_1?ie=UTF8&qid=1522460892&sr=8-1&keywords=Greenhouse+Overlap+Glazing+Clips

But I would prefer a local source, and i am on a budget

The problem is I have an image in my head of a longer clip that i have seen somewhere that would be ideal, but for the life of me i can't remember where or in what context

as ususal any help would be appreciated
