UPDATES

###2022-12-02

Released DRIP_TIP_V2; it really makes it easier to push air through, IMO. Print with threads facing up. Removed historical files. No one should be using those anyways.

2022-01-21

Released EXT_CHAMBER RC2

2022-01-19

Update 02
I. Tweaked EXT_CHAMBER and versioned first RC.
II. Moved old experimental models to archive.
III. Used the sploof ;)

Update 01
Added EXT_CHAMBER V4, no longer needs thread adapter, should be easier to print overall.

2022-01-09

Update 03
Moved EXT_CHAMBER V1 and V2 to archive. Released V3. Air vents near threading re-positioned further away.

Update 02
Added alternative EXT_CHAMBER model. Might be easier to print, but should keep the threads cleaner and I've moved the troublesome air vents inward. I haven't tried to print this version myself. It may be best to wait, I'll be tweaking this design more.

Update 01
Add experimental models to extend sploof body with an extra charcoal chamber. Print EXT_CHAMBER with the thread on the top, and EXT_THREAD with the text facing up, or the 14mm (littler) threading at the top. Printing the chamber I had a bit of adhesion issues because of the tiny air slits, as a tip, in Cura set Initial Layer Speed to about 10-15mm/s and set Number of Slower Layers to 1.8mm / Layer Height.

2022-01-07

Body model has been updated to allow easier filter install. Outer dimensions are the same, so you will not have to reprint the cap. I've also added an STL called TIP_PLUG that can be threaded in place of the drip tip to keep charcoal from falling out while traveling with it, when gifting it to someone, or for, ya know, whatever.

NOTES: Print TIP_PLUG with threads at the top, head facing down. The same as the drip tip shown in the additional notes.

2021-12-07

For those of you who have previously printed this before Dec 7, 2021, I have designed a nicer looking cap, and have made the WIDE version the recommended version to print. Going forward, all redesigns and tweaks will be based from this model. P.S. The fkSploof_HistoricalArchive.zip is only the older STLs, but kept for historical purposes. If you are interested in printing this design, I would not use those files from that zip.

ABOUT

This is my custom designed sploof that I am sure is not an original idea. That being said, I was not happy with the offerings on Thingiverse, and decided to make my own, in a style that is more than just a straight pipe with charcoal pellets. This style should minimize the the footprint while increasing the amount of volume, (or surface area) of filter.

ADDITIONAL PARTS (Used in featured makes)

• DuPont 3 Way Odor Control Carbon Filter
• Aqua-Tech Activated Carbon Aquarium Pellets

Feel free to substitute your own equivalent parts

ASSEMBLY

Assuming you are using my shopping list, you'll first need to cut your filter to size, just throw away the hard plastic grid the DuPont filter came with, we will not be using it here, sorry Earth. Your filter should be cut to 16mm in length and about 60mm in height. After cutting to size, I was able to start with getting a corner wedged in, and then using a plastic knife to work the filter down both walls of the body. You don't want to pack it to hard, so if you are getting resistance in one area, try working on getting it down in some other part before returning, air has to be able to pass through this, if you find it too hard to blow air through,you can remove 5-10mm of the filter height, and try again. The pellets add almost no resistance, so your kink would be here.

After you've somewhat successfully wedged your filter down the walls, you can also try and cutting one to size for the inside of the cap. I was able to do so by placing the cap down on the filter and just cutting the filter around the shape of the cap, then cutting an X in the center of it by folding in half and cutting it twice. You should be able to manipulate the filter around the threads on the cap. I was able to anyways. Screw in the cap. You can choose to glue the threading or not, I'd glue it if you are gifting it to someone, otherwise it can be reusable.

Turn the unit over, and start adding your pellets through the top, tap the body a little bit to get the pellets to settle as you are adding more. Stop when you get just under the start of the thread line for the drip tip. Cut another piece of filter to fit the exact space of the thread hole, and then screw the drip tip in, again, to glue or not is up to you.

There you go! Your own discreet smoke trap! I've actually been amazed at how well this works, but I haven't used other designed sploofs from here, so you'll have to let me know how other's compare.
