Using Delrin Clips for Mounting PCBs

Board Clips

So one of the problems with the Raspberry Pi board is the lack of mounting options simply because it doesn't have any mounting holes. A few nice injection molded enclosures for the Pi and other boards out there use a simple clips to hold PCBs in place, eliminating the need for additional hardware. I figured there should be a good, easy to make solution out there for those of us that can't get injection molded parts on a whim so came up with some nice laser cut Delrin clips that can be used with typical laser cut mounts (see above pic). Here's a video of the clips in action on a prototype Raspberry Pi sled I'm working on:

As you can see, they're pretty easy to use with a properly designed mount plate. There's a couple advantages the clips have over the standard bolt, standoff, nut mounting method. First, you don't have to have all the additional hardware bits, just some Delrin stock. Second, they make assembly pretty easy with no juggling of bolts and standoffs on boards (if you've mounted a PCB before, you're probably had the moment you realize you didn't hold one of the bolts in place as you flip the board over to tighten everything down as miscellaneous hardware bits fly everywhere). Third, you can make the standoffs a specific height if you need to easily since you're not limited to the standard heights that are available.

You can grab the files for my Raspberry Pi sled reference design on my Thingiverse page if you want to try them out for yourself!

I've also got them in my store here!

    Not to rain on your parade, but these things exist as standard product from people like RichCo.

    Those are cool but the ones I’ve seen still require mounting holes and aren’t super cheap. Are there clips for the edges of PCBs that they sell?

    talk about overengineering… just screw 2 plastic screws (or metal ones if you are sure there’s no problem) on each corner of the board…

    last time i checked screwdriver were much cheaper than laser cutters :)

    That works as well, but these are definitely more convenient for me. Again, this is probably because I’ve got access to a laser cutter, but hopefully most people will have access to a laser cutter a few years from now.

    I’m just honestly happy to see people out there really trying to design some cool things for the Raspberry Pi.
