OverlapStrap Fixit Blocks

“Fixit blocks” are the bread and butter for Bodgeit’s Repstrap Bertha and my own OverlapStrap design. They are convenient little fixing blocks sold by:

Unfortunately for people living outside the UK these blocks seem to be difficult to source. I am afraid that I also don’t have a solution for people wanting to buy these blocks from a supplier in their own country. However I am willing to re-sell packs of blocks via ebay, and ship internationally so if anyone is interested drop me an email. It seemed to me that also no one has drawn accurate drawings of these blocks for anyone who was interested in making their own. So here are the drawings below

The drawing is also available here as a DXF file.

Also for anyone trying to source these in other countries, here are some potentially useful search terms:
Modesty Block
Jointing Blocks
Knock Down Block
Knock Down Fittings
Fixit Block
Fixing Block
Cabinet Fixing Block
Viereck M̦belverbinder РGerman for: Quadrilateral Furniture Connector
Cupboard Connector Block

There is also something very similar, but not quite the same in the USA. I think in the USA they might be known as ‘Knock Down’ fittings/connectors.
