Made years ago with some recent tweaks added, including adjustable length options. The full version is surprisingly lengthy. A shorter version, simply called "Short," offers a more concise take. And for those who prefer an even more compact option, there's the "Mini" variant. These specifications were measured from a Cyma MP5 and printed out twice. To assemble this design, you'll need 4 M4 screws (measuring between 14 to 16 mm in length) and 4 M4 nuts.
