2" Laser Cut Blast Gate

thingiverse

I have not cut this yet but the sizes should be correct for using 2" PVC. Double up the smaller pieces on each side of the rectangular piece. For the siding gate, I would suggest a slippery material such as HDPE or UHMW plastic. Mounting holes are sized for 8-32 hardware. This is not a self cleaning design. I recommend mounting it so the slider pulls downward. That should help keep dust out of the grooves. Update 3/11/19 I've modified the file to be self-cleaning. I laser cut it out today and almost everything came out perfect (slight goof on the file that has since been corrected). All of the holes line up (orientation matters) and the hole for the two inch PVC pipe fits perfectly. I plan to cut the three pieces that were goofed up again, get some inch and three quarters 8-32 screws, glue it up, and post pictures. Look for those photos later this week. Update 10/5/19 I have removed the self-cleaning gate because I still have not updated the goofed up parts.
