I designed this with 123d beta - similar to autodesk inventor. http://www.123dapp.com/ This mount is for a Sells Mendel and has the wade's mounting holes - I measured everything with a caliper to figure out the correct measurements :)...Printed pics within the hour..and I will report if it has correct measurements or not. (I'm printing with a slightly incorrect mount right now with these linear bearings and they work a treat! - So smooth)Rencio outYou will need 4x SCE8UU linear bearings and M4 bolts and nuts. Search ebay for the linear bearings (worldwide).
