Quarter Inch Strap Base for Cameras and Trackers

thingiverse

Hey! Here is a platform which you can put a 1/4"-20 thread screw through and secure any sort of camera or tracker to. The bottom has a minor curve to better fit onto cylindrical objects, like a boot, tree branch, or bicep. The 1/4" - 20 thread thumb screw I used is .4" or 10mm in length from the bottom of the shoulder and pokes up .2" or 5mm above the top surface of the base. I bough them online. The base has 2 slots on each side for 1" wide straps or other flat objects. There are also two loops going around them for .175" wide zip ties to go through. Additionally, there are 3 vertical and 3 horizontal zip tie loops. You might be able to attach something like small tools or batteries to the side. The recoil lug is fully modular and optional. It is .2" in diameter while the 4 slots for it are .202" for tolerance fits. With PETG print, it is a finger push away. For PLA, it might be a bit harder to get in. I recommend using the lug in conjunction with HTC Vive Trackers to prevent them from spinning and losing orientation. Lastly, I've included a version called StrapQuarterFeatureless.stl which has no additional zip tie mounts and no recoil lug slots. That version is much simpler and probably stronger in extreme cases. Feel free to modify it!
