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.
I’ve tried a couple ideas – wood holders, washers and bolts – but nothing seemed to work well. So this week I decided to learn how to design and print 3D parts.Continue reading Dog Weight Scale Part 10: 3D Printing Load Sensor Holders
