This is a simple 20mm tall cold shoe extender designed specifically to be tight onto a Smallrig cold shoe and have enough room on top to mount a Rode Ryocote Lyre mount, such as is found on the Rode VideoMicro. The dimensions can be seen in the image above. I'll gladly share my design work for anyone who needs alternate dimensions. Print on its front to avoid overhangs and the need for support when printing with FDM (FFF) printers. Doesn't need to be printed solid, but you should have enough shells to have the tabs be as sturdy as possible.
