View this part on my website, and get links to the screws I used.
The "Thumboney" was created to add thumb screw-ness to knurled 1/4"-20 screws that are commonly found on DSLR/Mirrorless Camera rigs. You can use these screws to secure a lot of different camera and lighting equipment to whatever.
This part was designed to be used with an upcoming project, the Elgato Prompter Mod Kit, as a way to use a 15mm 1/4" screw, but keep the build low profile by using this thumb-screw adapter to tighten and loosen. While this part will be sold with the whole kit, I wanted to upload it in case anyone else wanted to print it for themselves.
This was one of my first designs from scratch, and it's no where near perfect or well designed. BUT THIS IS MY RIFLE. THERE ARE MANY LIKE IT. BUT THIS ONE IS MINE.
