Right angle polar scope adapter for Sky-Watcher Star Adventurer 2i

thingiverse

This is an adapter to mount a popular/common [Amazon 90 degree viewfinder](https://www.amazon.com/s?k=right+angle+viewfinder) to a Sky-Watcher Star Adventurer 2i polar alignment scope. The combination makes polar alignment **much** easier and more comfortable, particularly at higher latitudes. The 90 degree viewfinder I have is branded Azeyz with 1x and 2.5x magnification but there are multiple Amazon vendors selling the same unit. The three retaining screws are M4x16 bolts with M4 nuts, both should be readily available at nearly any hardware store. I put a layer of tape on the polar scope barrel to protect it from being marked by the screws. The retaining knobs and caps are courtesy of [Thing 4558217](https://www.thingiverse.com/thing:4558217) and I secured them with a small dab of polyurethane glue. I didn't actually use the caps but they are included in case you would like to. I recommend printing as oriented in TPU with supports everywhere on a well calibrated printer. TPU was chosen for durability and some flexibility in achieving a snug fit. The tolerances are close and may not work with rigid material or a poorly calibrated printer. This design was inspired by [Thing 3473034](https://www.thingiverse.com/thing:3473034) and [Thing 2801479](https://www.thingiverse.com/thing:2801479) but after trying both I decided to create my own design. **PLEASE DO NOT PRINT OR REMIX FOR COMMERCIAL SALE**
