Home brew pressure bottle filler

thingiverse

I’ve used this pressure bottle filler for over two years and it has been well worth the effort to mount it on a sturdy frame rather than hold it by hand. Here are all the STL’s and I have included step files in case anyone wants to tweak the design and make a remix Things to note: The two aluminium rods I used were about 5.9mm diameter, if you need to use different rods then you will need to alter the “rod holder.stl” or the “rod holder.step” file. I am not sure if every bottle filler of a similar design is of the same dimensions so I have included a link to the one I purchased from UK amazon. I purchased it a few years back but hopefully they are still selling the same one, I did notice that it has increased in cost, I paid about £33 at the time. https://www.amazon.co.uk/gp/product/B07TQT33DP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 You will need to use 3mm brass inserts in the back of the main body to mount the top and bottom sliders (see picture), I used 3mm x 20mm long socket cap screw when mounting. The two top clamps were held on by dry-wall screws about 20mm long. To mount the rod holders to the stand I used number 8 countersunk screws (4.2mm dia) x 45mm long. All the parts were printed in PLA except the Twist Lock which was printed in PETG to make it a more durable. If you need to know how to use one of these pressure bottle fillers then look on youtube.
