Makercase (makercase.com) has released an updated version that allows you to adjust the tab size for Finger and T-Slot joints. It's limited to 1/2 the smallest side of your box but this is a great addition to this handy application.
The adjustment shows up as a slide under the box picture when you select Finger or T-Slot. Below are two examples of a box adjusted for different tab sizes.
I'll be teaching a class at Microchip Master's this year about how to create a prototype circuit board with ExpressPCB. This should be fun and hopefully it goes well. I used a lot of the material I created for a future book on the subject and this class will give me feedback from new users what they are looking for on this topic.
If you aren't familiar with it. ExpressPCB is a free PCB and schematic software that makes it easy to create low cost prototype boards. You can get three for $85 with solder mask and silkscreen. You can get them for less if you go for a bare board. I like to use them to prove out a design.
From there I can check their pricing for higher volume or order the gerber files for $60 and have it quoted elsewhere.
If you are attending Master's stop by the class and say hello and let me know you follow the blog.

Chuck has been programming with PIC Microcontrollers since there were only five devices. Now there are over 700 and growing. He also has a lot of fun 3D printing designs using his Davinci 3D printer and TinkerCad software. In this series of blog posts and occasional videos on his YouTube Channel he tries to help you get started with electronics and 3D printing.
