Now, what could be more fun than Jenga? Jenga with guns!
This laser cut Jenga pistol contains a rubber band powered captive bolt which allows you to knock the blocks from the tower at never before seen speed and allowing you to perform feats that'll amaze your friends. Originally seen at Woodgears, this version's designed to be cut on a laser cutter and is an upgrade on the acrylic version that I previously made. It's easier to put together and requires fewer nuts and bolts.

Step 1: Design
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.
