My 3D printed repair is complete. A long journey but a perfect fit in the final product.
Using Meshmixer has a steep learning curve. But it works so well that learning to use it is fun.
In my previous article I described using 123D Catch to create a 3D model from ordinary pictures. Here’s how you can manually fix stitch pictures together into the 3D model when 123D Catch fails to do so automatically.
In a previous article, I began using 123D Catch to create a 3D model from still photographs. My project is to print some replacement feet for a patio chair. These were originally made from injected molded plastic. Several have gone missing over the years. Before I can print the replacements, I need a model. I can create this in CAD, or by using 123D Catch. I thought the latter would be easier and faster. But from where I am on the learning curve, it might not be.
Several of the plastic feet on my patio chairs have gone missing over the years. I should be able to do a 3D part replacement by printing some new ones. That will be the easy part of this project. The difficult part is coming up with a 3D model of part. Since no one has published a 3D model for this part on Thingiverse or elsewhere, I am on my own.
It’s fairly easy to connect to a remote 3D printer from any computer in your home. That includes tablets and phones. Here is how I did it.
My 3D printer now does auto-leveling using a proximity sensor and an external control board. This DIY PCB article describes completion of printed circuit board used in this project.

It’s amazing that after so many years with radio and electronics hobbies, I had never created a DIY PCB scratch. Oh, sure, I have used printed circuit boards made by others many times. These were either purchased commercially, or fabricated to my design. But it was time to make my own. So, here goes.
Many people begin to use a 3D printer for making toys, models, jewelry and art. These are more aesthetic than practical. But there are many practical ways to use a 3D printer around the house or workshop.
Getting the first layer right is the holy grail of 3D printing. This is hard if your print bed is not completely level. Here’s the story of why and how I added 3D printer auto leveling to my Sunhokey Prusa i3.
