Holography lab parts

<h3>This collection of printable parts is designed to set up a fully functional holography lab, and will continue to be updated as time allows.</h3> The magnetic base was inspired by the open-source design created by jpearce, which can be found online. To assemble it, you'll need three 1/4" magnet cubes, one M3x12 bolt, and a M3 hex nut. Alternatively, you can print the base without slots for magnets. It's made from 1/2" round bar, just like all of the clamps. Printing with a brim is highly recommended. The two-part right-angle clamp requires four M3x20 bolts and four M3 hex nuts to assemble. To create a left-handed version, simply mirror the design. The first part of the clamp is designed to work seamlessly with many other parts, including lens holders, laser diode mounts, and shutters. Some parts are designed to mount along the rod rather than perpendicular to it, like fixed mirror mounts. The clamp connector serves as the base for these types of parts. A cylindrical platform mount for a helium-neon laser is also included in this collection, which sits directly above the magnetic base and connects to a 1/2" rod. For secure mounting, use two of them. Each one requires two M3x12 bolts, four M3x10 bolts, and six M3 hex nuts. To mount the laser as low on the table as possible, cut the rod to a length of 2 1/2". It's a good idea to use PETG for at least the tube clamp piece, since the laser tube can get very hot. The shutter requires one M3x8 bolt, one M3x12 bolt, two M3 hex nuts, a 1/4" x 1/2" x 3/16" (R188) bearing, a 1/4" cube magnet, and some 28 or 30 AWG magnet wire. A bobbin is also provided for winding the coil. Check out this video to see a hologram shot using these printed parts: https://youtu.be/ei3Cr9MSqPI
