IMPORTANT: I made the part with silly units, so it looks super small. Scale it by 2540% and it should be the correct size. (Inch to mm conversion, silly me)

Holds six chisels, up to 1 inch (25 mm) blade size. Has pegs on the back meant to connect to standard 1/4 pegboard. There are two holes for screws as needed. Size of the holes are 0.25 inch. For me, it was helpful to have some pine backing on the other side of the pegboard. The ¼ MDF pegboard does not provide a ton of support. There are mouse ears on the part to stop corners from coming up if that is a problem. Those are easy to cut off, and the part still looks decent. 

Measure your chisels first, most will fit, but better safe than having wasted time on a part that will not fit your chisels. I used this for my Irwin Marple chisel set. Not too good, not too bad.

This is actually the second iteration of this. The first was very bad and I am embarrassed to post it here.
