3D Printing 3d printed launch rod holder

[curtisheisey]

Inspired by a rocketryworks.com design (who is closing their doors soon), I whipped up a launch rod holder that uses 10-32 thumb knurled knob to hold the rods in place. I made two variants. One configuration holds 1/8, 3/16, and 1/4 inch rods. Another configuration will accommodate a 3/8 launch rod post for monocopters and bicopters. It has mounting flanges to go on a 2x4 to be inserted in a jawstand. It can probably be mounted to a 1010 rail with t-nuts, but I haven't tried that.

I printed out of PETG, 60% infill. Printed without supports

Enjoy,

Curtis

Here is what the one for the 3/8 launch rod post looks like, although it hasn't finished printing.

Zoro has some nice knurled knobs https://www.zoro.com/kipp-star-grip...-black-k01554a1x20/i/G3334816/#specifications

The 10-32 nuts are standard 3/8" x 1/8".
