I use carbon fiber and glass fabrics to vacuum bag glider wings so I have a supply at hand usually .The depron foam is relatively high density stuff that has been used to form rc airplanes out of besides whatever commercial use it started out as and can be had in most craft stores I think in various thicknesses from 1- 6 mm or so.I just used some white EPS foam for the form and wrapped cling wrap around it before laying up the carbon fiber fabric .Then after the 4 layers and the depron bottom layer were all wetted out over the block I wrapped the whole mess tightly in cling wrap again trying to avoid any wrinkles that might show up and let it cure a couple hours before I trimmed it to basic size.

Really took me less than an hour to do and cost very little since I had scraps laying around and epoxy is still relatively cheap
hope this helps
