About this model

So I needed a design that I could give to all of my long-distance paramours this past Valentine's Day. I decided on a variation of my recreation of Ludwig Oeschlin's Dual Ulysse escapement since it naturally fits within a heart shape. I explain that this model is to "count the seconds we're apart." Currently it is only hand-powered since I could not get my elaborate, ratcheting going-barrel to work with it. I guess we could debate the merits of the immediacy and personal interaction with the hand-powered version vs. the design and sophistication of the spring-powered version. Once the spring motor is more reliable, I'll upload it. Tolerances are pretty tight on this design (as with all radial-thrust escapements), so be mindful of how it prints (avoiding over-extrusion and elephant-footing)…
