Grow tent space booster

I purchased a grow tent that has these "space boosters" inside, which in reality are simply horizontally fitted, 16mm thick poles intended to prevent the walls of the tent from getting sucked in too much by the negative pressure caused by the extraction fan. One of the hangers for these poles broke the instant I dropped it, and this was designed as a replacement. These could be used to create a similar structure of your own, all you need are poles of correct lengths for each wall of your tent.

Depending on the material used and the weight of the poles, yours might slide down or not. I made this in PETG and have had no problems. The tolerances are quite tight to prevent sliding so make sure to make them solid, brittler materials might snap.
