T-Nut Spacer - Spyder3D World
Spacer for use in assembling parts using 20mm t-slot extrusion, useful when the t-nuts need to be aligned and are inaccessible. The stl file is only 1mm high, you’ll need to scale it to whatever height you need. Btw, cut straws work for this purpose too, they just don’t stay in quite as well. Printed in NinjaFlex, and in vase mode, which makes it possible to insert the spacer post-installation.
