These are our 45 degree clamp assists for framing and miter joints, as shown in our piano legs build video. The unique design is meant to allow for maximum positioning of your clamps, with strategically placed posts in the design which give greater control of the directed pressure. The jigs also include presized adhesive backed cork for maximum grip, and excellent protection of your workpiece. 
 
There are 2 size options available, the smaller size is not an exact scaled version of the larger jig but rather an adjusted design where the posts are repositione....this allows the clamp heads to still fit well throughout the jig. 
 
Each clamp assist is printed in PLA+ with a 65% infill, and extra walls for excellent strength.
