stable usb microscope stand

thingiverse

Just like many others, I found the cheap USB original microscope stand utterly useless. However, I didn't want to go out and buy rods and such; instead, I wanted to create a more affordable design. I used a rack-and-pinion system to regulate height, allowing for smooth control of the microscope without any wobbling. To tighten the axle nuts and bolts to your desired level of firmness, simply apply as much force as needed. Here's what you'll need: * Three M3 nuts and bolts approximately 12-15mm in length to secure the axle and prevent it from sliding on its own, while also keeping the microscope firmly attached. * The holes are 3.4 mm in diameter, equivalent to about 1/8 inch - for those who prefer to work with imperial measurements. To print this design: * Use supports during the printing process. * Set your layer height to 0.15mm. * Refer to the image provided for recommended print orientation. * If you find that the movement is not smooth, try reducing the layer height or increasing the surface quality of the pinion.
