T-Shank Jigsaw Blade Holder for Wall Control with multiple sizes

This is a combination of Jerrod H's T-Shank Jigsaw Blade Holder and Luma's DDD Printable Wall Control System. I loved the original T-Shank Blade Holder by Jerrod H, but it was simply too big for my needs. I have remixed it to have options for 12 blades or 20 blades, rather than the original that held 36 blades. No supports needed to print.
