Customizable square clamp
thingiverse
Following Instructable at http://www.instructables.com/id/Clamping-Squares/, use this tool in conjunction with standard clamps to securely hold a picture frame in place. The installation concept is illustrated in the second image of the gallery. For printing, utilize the Customizer to generate an STL file tailored to your specifications. Alternatively, I suggest crafting the tool from wood using laser cutting or traditional CNC machinery. To do this, download the SCAD file, change "output_type" to "DXF," and export it in DXF format for use with your chosen material.
With this file you will be able to print Customizable square clamp with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Customizable square clamp.
