Stand for a DS0138 digital scope kit. If you want to re-render the stl's you will need to be clever and change the source to re-mirror for left and right sides. Oh, please note that the left and right sides are labeled backwards :)

Use two peices of 6-32 all-thread to hold the two pieces apart.

Nut | stand left | nut ------- Nut | stand right | nut

The two sides act like a clamp to hold the pcb, space the nuts just like on the mendel i2 to hold the pcb without squeezing it to death.
