This is a version of the tabbed joint plyometric box commonly used in crossfit. I practiced drawing it up in fusion 360 to gain a little experience in drawing and sorting out mistakes using CAD prior to any actual cutting. Then I used a cut list optimizer to plan out plywood sheet cuts to limit scraps/excess, and then batched out 5 boxes.

The dimensions are 30” x 24” x 20”

Very nice. I recently had a discussion with one of my friends about these. The commercially available ones carry a very high price tag and are not anywhere as nice as this one! Great Work!

I like it. Please share with us how you cut the plywood to form the tabs.

Thanks everyone, I forgot to mention there is an internal panel mortise and tenoned for span wise support.

How I cut the tabs… I cut out all the panel blanks first and with the scraps I made a replica of each joint of the box as accurately as possible with a band saw to use as a template. Once I successfully fit check the templates to each other I clamped them to my stock and routed out the part with a pattern bit. Once I made one of each side, I used that as my full size template. I used the same one over and over to prevent tolerance stack up. Also, prior to routing I drilled one 1/4” hole in each corner of each tab to help with fit. I used the same template idea for this, measure once and transfer all the rest.

I hope this all makes sense!

nice, rounding over the corners will do wonders to save shins, good job
