As a user of many of these coupling devices, I would highly suggest buying your couplers pre-fabricated and avoiding many hours (and possibly days) of headaches trying to manufacture these with your own hands.
Rigaku Reagents sells them: https://www.rigakureagents.com/p-516-wizard-cubic-lcp-kit.aspx Formulatrix sells them a bit cheaper: http://formulatrix.com/store/product.php?productid=27&cat=4&page=1 I have used both products and they both function well even after many uses and cleaning cycles in methanol.
