Pre-separator / cyclone for all-purpose vacuum cleaners using IKEA SAMLA boxes

Tried to create a cheap alternative to the metabo and starmix models. The cyclone is placed on an IKEA SAMLAs lid (11/22l or 5l) while the corresponding box can be used to collect the dust.

I even did connect two in series to improve separation performance and could see dirt in both boxes (way less in the second one).

The model was designed to fit a prusa mini print bed. The lower ring was printed upside down (flat surface obviously). The upper part was placed on the hose connection surface upstanding (see attached picture).

I used M5x15 screws to mount the lower ring with the cyclone part.

Connections for hoses are designed to fit my needs / which hoses I had lying around. Will implement osVAC neo connections in the future eventually to fit everyones needs.

The lid is pretty rough to cut (be careful). I used a cutter knife, hot wire cutter did not really work out for me. Please feed back if you find a better alternative :)

Also the box warps quite a bit but did withstand my metabo portable vacuum even if the hose was clogged. Please feedback if a stronger vacuum cleaner bares the risk of damage to the box. Already thought about implementing an under pressure safety valve.

Other improvement suggestions are welcome!

Also feel free to improve on your own but let me know about the result :)

Adjusted both versions without helix on request to improve the centrifugal effect. Downside is that the model builds up higher and printing propably requires support NOT YET TESTED! Feel free to provide feedback :)

I just created an adapter to mount the SAMLA box to a metaBOX. Models can be found in my profile.
