Here is a simple hold down clamp system to secure 1/4" plate to your CNC Router. Simple design that can be printed or milled. and works wonderfully.
It all started with Sketchup ( as it always seems to lol ) I knew the thikness of material (0.250) I needed to secure and that I would like to secure it in each corner.
Perfect! Everything seems to be how I need it now off to the 3d printer ( handy little things, if you don't have one yet: check out all the cool builds in the builds section of openbuilds a lot of designs to choose from )
And bam! I come back from breakfast with parts fresh off the printer ready to be used.
In place they do a great job of holding and securing your material in place. No way to move your plate around... Even when I crashed my end mill deep in to the aluminium and ran off course ( I mean when I took artistic freedom and changed design mid production ) the plate did not budge!
Feel free to make some up for your self! If you do let me know how they turned out..
Happy building folks..
