M4 Hadley primary mirror holder

Update I have a newer model which solves an issue with the screws pushing on the mirror: https://www.printables.com/model/289164-m4-primary-mirror-cell-for-hadley-w-keyhole-slots 📷 Image redacted — claim this model to add your own media Description I couldn't find an M4 version of the primary holder so I made my own. This is a modified version of the Hadley primary mirror holder that should fit m4 hardware. It also has a slot that you can slide the nuts into after gluing the mirror, so you don't have to worry about forgetting to put a nut in. I've used this in my own telescope and have been getting amazing views of the planets 🙂 Assembly If you remember to put the screws in first, you can also put the screw head under the mirror, with a nut run all the way to the top as pictured. This ensures that you don't overtighten the screw and push on the mirror (which, in my case, led to the mirror falling off) 📷 Image redacted — claim this model to add your own media
