The original Modular Hydroponic Tower Garden is designed by boundarycondition on Thingiverse: https://www.thingiverse.com/thing:3405964 (Modell do not exist anymore)

I designed a new lid adapter to fit the car wash bucket from Biltema https://www.biltema.se/bilvard/exterior-bilvard/tillbehor-for-exterior-bilvard/biltvatthinkar/biltvatthink-20-liter-2000042355

The hole model from boundarycondition can be downloaded on https://makerworld.com/en/models/65860?from=search#profileId-78967

You have to cut a 120 mm hole in the lid, Can be a little bit tricky but it´s possible.

The mount went out very steady.

It´s mounted with 8 pcs M8x30 bolts (Stainless is best)
