Isolating Printer Feet (D-Bot / V-Slot / Aluminium Extrusion) using Springs

thingiverse

I never knew what vibration was until I finished building my D-Bot CoreXY machine. The structural integrity of my home was at risk when I first ran it on the floor, so I designed some damping feet that would be easy to produce cheaply. Note: These feet caused issues with high-speed/acceleration/jerk settings and are being redesigned to include seven springs each currently. This is now my final complete design which has been printed, tested, and installed successfully on my printer. I have changed the springs I am using (the link below has been updated). These ones are slightly smaller and a bit firmer - they work great and I would be confident putting up to 10 kilograms of load per foot, maybe more. Each foot consists of: 1 x Printed 'Spring Feet Top.stl' 1 x Printed 'Spring Feet Bottom.stl' 4 x Springs (http://www.aliexpress.com/item/3D-printer-accessories-Ultimaker-2-UM2-spring-fine-print-platform-edging-1-2-15mm-for-UM2/32606455778.html?spm=2114.13010608.0.108.bIz7v1) - buy one pack and you can make seven and a half feet 1 x 3M 'Bumpon' adhesive rubber foot circular/flat 20mm x 2mm (or cut your own from cork, etc.) Assembly should be pretty self-explanatory from the renders... Prepare the bottom part by placing four springs in the holes. The springs should fit relatively snugly on their own and the assembled foot will easily hold together without additional adhesive. Put an M5 cap head bolt into the hole in the top of the top part (you may need to drill out the hole depending how accurately your print turned out - but with a bit of force you should get the thread through and head in the recess without this). If printing ABS, scale up to allow for shrinkage. Line up springs with the top piece and push everything together. Attach to the bottom of the printer/equipment using an Allen key through the hole in the bottom of the bottom part. Place a 3M bumpon foot into the recess on the very bottom.
