While it’s true that we didn’t specifically say making Hackaday staff exceedingly jealous of your good fortune would deduct points from your entry into our ongoing “Repairs You Can Print Contest”, we feel like [Sam Perry] really should have known better. During a recent dumpster dive he found an older, slightly damaged, but still ridiculously awesome Mantis stereo inspection microscope. Seriously, who’s throwing stuff like this away?

Apparently, the microscope itself worked fine, and beyond some scratches and dings that accumulated over the years, the only serious issue was a completely shattered mount. Luckily he still had the pieces and could get a pretty good idea of what it was supposed to look like. After what we imagine was not an insignificant amount of time in Fusion 360, he was able to model and then print a replacement.

The replacement part was printed on a Tronxy P802M in PLA. Even at 0.3mm layer height, it still took over 10 hours to print such a large and complex component. A few standard nuts and bolts later, and he had a drop-in replacement for the original mount.

Whether it’s due to how big and heavy the Mantis is, or a slight miscalculation in his model, [Sam] does mention that the scope doesn’t sit perfectly level; he estimates it’s off by about 5 degrees.

We’re somewhat suspicious that mentioning an error of only 5 degrees is a stealth-brag on the same level as telling everyone you found a Mantis in the trash. But if [Sam] gives us the GPS coordinates of the dumpster in which people are throwing away high-end lab equipment, all will be forgiven.

There’s still plenty of time to get your entry into the “Repairs You Can Print” contest! The top twenty projects will receive $100 in Tindie store credit, and the top entries in the Student and Organization categories will each receive a Prusa i3 MK3 with the Quad Material upgrade kit: arguably one of the best 3D printers currently on the market. If you were considering going back to school, or finally leaving your basement and joining a hackerspace, now would definitely be the time.
