The jenga pistol was designed in a trial version of Alibre Design
, my favoured CAD package.
I went through several iterations to get to this stage with various attempts at getting the plunger, trigger and plunger guides correct. While designing it I wanted to keep it as simple to build as possible, with minimal screws and bolts holding it together. The trigger was designed so that it was its own spring, I didn't want to have to use a spring or a rubber band like in the acrylic jenga pistol
that I made last year. The joints holding the pistol together are all interference fit, designed to either fit together tightly with no modification or after a very light sanding.
A laser cutter would be the tool of choice for this project, but it could easily be made with a paper template glued to 1/4" ply and then cut out with a scroll saw or a coping saw.
The files for either method are attached in this step. I've included:
1) The DXF files for laser cutting or for printing 1:1 scale to glue to wood
2) An EPS file, converted from the DXF files. Some laser cutters prefer this.
3) A PDF of the Alibre model. You can open this, click it and then use the controls to rotate it and look around the model.
4) A zipped copy of all of the Alibre files for opening, viewing and modifying.
