Magnetic chisel holders for a standard set of 1/4, 1/2, 3/4 and 1 inch wood chisels.The printing involves two pieces; the base that goes into pegboard and the holder that holds the chisels using a magnet. I used a rare earth magnet and magnetic cup available from Lee Valley Tools.. This thing is designed for pegboards with 1 inch spacing like those sold by Home Depot and other home improvement centers. www.leevalley.comhttp://www.leevalley.com/US/wood/page.aspx?p=32065&cat=1,42363,42348 3/8" diameter circular magnet Part# 99K32.03http://www.leevalley.com/US/wood/page.aspx?p=32066&cat=1,42363,42348 1/2" diameter for 3/8" magnet steel cup Part# 99K32.52 Optional High friction discs for 3/8" magnets Part# 99K34.51Settings (Suggested) Raft: On Supports: On Infill: 80% Suggested to make sure 'pegs' are strong. Shells: 3 Layer Height: 0.20mm 1) Print 4 bases. After printing, clean raft and supports being especially careful around the pegs. Remember to clean around both pegs. File as necessary for good fit in pegboard. 2) Print chisel holder for each chisel you want to store. Clean raft. 3) Using a #43 drill, clean out the four smaller holes on the back of the chisel holders. Be careful not to drill through the body of the holders. 4) Using 4-40 tap, tap the holes you just drilled in the holders. 5) Using a #33 drill, drill the remaining hole in the holders. This is the hole that holds the magnet cup. 6) Using the same #33 drill, drill through the 4 similar holes in the base. These will be used to fasten the base to the holders using 4 4-40 x 3/8" machine screws. 7) Using a flat surface and some sandpaper, make sure the backs of the base and holders are flat and free of any burrs. 8) Insert the 1/2" magnetic cup in the recess in the holder. It might take a little persuasion but should be close to flush with top after insertion. 9) Position the base and holder so the 'L hook is on the same end as where the magnetic cup will be (the rounded end). Line up the holes of the base match up with the holes in the holders with the end of the base at just about at the end of the holder. 10) Using 4 4-40 x 3/8 machine screws, fasten the pieces together using the holes that were just tapped. Tighten so there is a good fit between the pieces but don't overtighten. 11) Using 1 #4 x 1/2" wood screw, fasten the magnetic cup. The screw should line up with the appropriate hole in the base. Tighten but don't overtighten.
