Mat Cutter

thingiverse

Mat board push cutter, similar to a Logan push style bevel cutter, cuts 4 ply mat board (~1/16") with a set angle of 52 degrees. Designed for efficiency, this build features 7 unique parts: two 3D printed components, a razor blade, melt-in style nuts, and three sizes of #4-40 screws. To accommodate different needs, I can redesign the cutter with smaller holes for tapped or self-tapping screws, or modify it to cut thicker mat board (up to 8 ply, 1/8") while maintaining the centered cutting mark on the unit's back. To assemble, start by cleaning up any rough edges on the printed parts. Next, press in the #4-40 nuts using a fine-tip soldering iron until they're flush or slightly below the surface. If necessary, file down any excess plastic and re-tap the threads to ensure proper function. Attach the base and blade holder with the #4-40 X 1/2" screw, tightening it until some resistance is needed to rotate the blade holder - use your own judgment here. You can apply a small amount of Loc-Tite to the screw, but avoid letting it come into contact with the plastic, which could cause brittleness over time. Install the blade onto the holder and adjust the cutting depth by setting the screw on the bottom or base. The blade tip should be just below the material's surface. Once assembled, start cutting or watch a Logan mat cutter tutorial video on Youtube for guidance.
