For the installation of decking

this is for 87mm wide 18mm thick boards 

5mm spacing for boards for proper drainage

15mm spacing from the edges for the pilot holes

It can be used for any size board just drill the first home slide print to the side install screw(s) 

If board is wider than 87mm then rotate to the other side for the second screw

16mm tab for board spacing 

Long tab for alignment to beam/joist

3mm hole for piolet hole

Upper tab for easy sliding and removal

Recommended printing in something like PETG with at least 4 walls as it will need to be strong to deal with the clamping pressure

originally printed with 3 walls and only the Tab broke but was still usable. 
no photos of the print as i have since lost it

Excuse the Shoddy Decking using the old decking but the previous person installed it with no gaps.
