Orion ST-80 Telescope Clamshell
thingiverse
Many astrophotographers mount their primary OTA on top of an Orion ST-80 as a guide scope. The ST-80 is typically secured by 2 ring holders, but I've always been dissatisfied with the flimsiness of rings, especially for such a large and lengthy guide scope. To address this issue, I created (from scratch) a modified version of Jeremy Jackson's clamshell design, tailored to fit the 90mm outer diameter of the Orion ST-80. All holes were designed to accommodate M6 bolts at maximum capacity. I've included the SketchUp file so you can modify this clamshell design to suit your needs if desired.
