With maple syrup season fast approaching (4 months ish) my thoughts have turned to working on the Sapmaster once again. I'm going to design and build a new top and bottom board this year to fit in the BUD DMB-4774 DIN case that I use for the SapMaster controller. That's going to involve a bunch of SMD soldering which reminded me of the irritation that soldering with loose pieces of SMD tape causes me.

To that end, I went looking for an SMD dispenser cartridge that would meet my needs. I couldn't find one so I decided to design my own.

This is version 4.1 of the design. It holds around 5 feet of standard 8mm paper tape which is around 1,000 components. The tape comes out the straight slot at the upper right. The clear cover tape goes out the curved slot and can be hooked under the little pin upper left. The point of the splitter between the straight and curved slots holds the components in place so they don't fall out before you pull the tape out of the slot.

I will generally use single cartridges with a cover but the friends I work with say that they want them to connect together. I considered a number of options but they all involved pins and holes or tabs and slots and I wanted the individual covered cartridges to be nice and clean. What I settled on are the holes you see around the corners of this cartridge. The accept a standard LEGO Technics connecting pin and allow you to gang together any number of cartridges.

I'm all setup to make versions for different widths and thicknesses of tape as well. The cover has four LEGO Technics like pins to plug into the holes in the cartridge.

I expect to start printing some to actually use in a few days when the magnetic base plate for my 3D printer arrives.
