Universal Post Mount STL


This ultra compact universal post mount can fit virtually anywhere and is perfect for creating a mounting structure on smaller props such as 24″ snowflakes or anywhere where the larger universal mounts don’t fit. With a footprint just barely bigger that 3/4″, if you have room to place a nickel on your prop, you can fit one of these mounts. Rather than using zip ties, this mount attaches to the prop using a single 1/4 x 20 screw in combination with a washer and a nut. The screw is inserted from the front of the prop with a washer and then on the back of the prop it threads into the post mount and is tightened against the embedded nut. This creates a strong post mount that is perfect for light to medium weight props. Versions for 1/2″ and 3/4″ EMT as well as 1/2″ PVC are included with the download. More info listed below.

Note: This is a digital purchase for STL files and not a physical product. 

For each post mount you will need a 1.75″ long 1/4 x 20 screw or bolt, a washer (fender preferred if there is room) and a 1/4 x 20 nut.

Start by drilling a 1/4″ hole through the coro where the post mount will be located. Then prep the mount by inserting the 1/4 x 20 nut into the mount. It’s often easiest to temporarily insert the screw from the bottom of the mount and threading the nut onto the screw. As you tighten the screw it will pull down the nut and seat it in place. To install the mount insert the screw with the washer from the front of the prop and thread the screw into the mount on the back. Then orient the mount as desired and tighten down on the screw to hold everything tightly in place.

Note: The 1.75″ screw / bolt is an odd size and is not commonly carried by the big box stores. This size is required to maintain a constant mounting height across all of our mount designs. If not available, you will need to either cut a 2″ size down to 1.75″ or predrill the EMT / PVC so that it can accept the longer end of the screw or bolt.
