Hello everybody! I've bought a professional knife set at the last Black Friday at Amazon store: http://amzn.com/B002ZCKIBM the knive set comes without block so I created one. I inspired from this awesome idea: https://www.instructables.com/id/Knife-Block/ and I remixed the project for FDM printers. I wolud speak about safety because this thing will be at home and the knives may be dangerous, so it's great idea if you follow three important steps below: 1) Use magnets as described on the project, you can find here: https://www.amazon.it/Magnetastico%C2%AE-neodimio-frigorifero-permanente-interattiva/dp/B00Z7YVU8A 2) Use rubber pads, print them with TPU95 or other rubber filament 3) Create the ballast, I hope you can create it with milling machine, the one in my project have a weight of 2.3Kg You need these hardware: Phillips flat head self tapping screw 4.8mm x 22mm: 2pcs Phillips flat head self tapping screw 5.5mm x 25mm: 2pcs Neodymium magnets 8mm x 3mm: 4 pcs Check everything else on the PDF and pics.
