0.5cm/1cm Deck/Board Spacer
This is a 1cm spacer to put between boards when building a wood deck. I used it for approximately 35 boards and it has worked great so far. It has big enough holes for gloves. Print it in the standard orientation. The files also include a 2 piece set of them.
Update: Added 0.5cm spacer
Update: Added source file for 1cm spacer
I hope this is useful, thanks!
