One of the things holding me back from 3D printing for so long was learning what tools I needed and how to use them. It’s relatively easy to print things once you have a design: Cults3D, Hubs, and many others (including your friends who have printers) can print your designs, your local library may have printers for you to use, or you can buy a printer for a few hundred dollars.
One of the last steps of assembling a Prusa i3 MK3 3d printer is to manually adjust the Z height. As I adjusted my printer’s Z height, I began to wonder what the Z height calibration looked like on my older printer, a Lulzbot Mini. At the same time, I became curious about what size that Lulzbot Mini can print. A simple test print answered both questions.
“Do I have enough filament to print this one thing?” That’s the question on my mind whenever I’m nearing the end of a reel of filament. I can’t stand wasting a few meters of filament by underestimating what’s left, and I don’t want to unwind a few meters of filament just to measure it and wind it back on the reel.
In my previous post I soldered the weight scale parts to a proto-board. In this post, I design and 3D-print the part that keeps the Load Sensors from slipping.
The Load Sensor is an oddly-shaped thing that has a few tricky constraints: the T-shaped part in the middle must be free to bend downward (my wooden mounts take care of that), and I don’t want it to slide out of place horizontally or tilt off of its position when I’m putting the top plywood piece on the scale.
