Sony RX100m1 shutter release & centering ring

prusaprinters

<p>A friend of mine wanted to use the BULB mode to shoot night scenes on his RX100M1. It doesn't accept any electric shutter release, and so this is what I came up with. It allows him to lock the shutter down for as long as he wants. With a less sturdy tripod it might still be necessary to cover the lens before and after, incase of movement.</p> <p>Shout out to Motorpixiegimbals on Thingiverse for the centering ring adapter, saved me lots of time.</p> <p>There is a through-hole on the bolt so that it might work with a mechanical shutter release trigger. If somebody has one and can spec the threads, I'd love to integrate that compatibility.</p> <p>It uses a small taper head M3 bolt &amp; heat set insert for the knob, but it functions without. (McMaster Carr 94180A331, 92125A128)</p> <p>I've also included a plastic tripod bolt and nut.</p> <h3>Print instructions</h3><p>Unassociated tags: Shutter Release</p> <h3>Category: Camera Summary</h3> <p>A friend of mine wanted to use the BULB mode to shoot night scenes on his RX100M1.

Some droop on the bridging but it works just fine.</p> <p>For a loose fit, I scaled down the screw portion at 99%, but a dialed printer should work too.</p> <h3> Post-Printing</h3> <p>Heat set an insert into the knob, use a screw to secure it in place. I put some loctite on there so that the knob and screw spin freely.</p>
