Worked great! Even with the large model!

These also worked great! They have the same sliding flap the lids attach to the boxes so you be confident the funnel will not slip out when filling. Thanks!

Printed the front and back rows with the middle hygrometer position. Everything fits great, it's easy to fill with the funnel another user posted as a remix, you can find it in the Remixes section. The hygrometer reading went from 30% to 10% in a few minutes after filling the boxes. This is awesome!

Printed great both times! Since it's usually te header part of the fitted sheet that comes lose, I'll try to save material and use only 2 of these. Might change my mind but it's worth a try. Thanks again!
