Lift Platform 3D Printed

grabcad

This is a light-weight adjustable height platform used to lower my plant seedlings as they grow taller under the inside grow lights ... Could have added more inner supports such as All-Thread all the way across between the center pivots, and also between lower wheels, for less side-to-side sway; however, I just need it to occasionally lower/raise, and wish to use the inside area for storage of planters and water bottles, etc ... Purchased the metal items from LOWES hardware store: 1/4" Bolts, No.6 screws, galvanized metal (18mm O.D.) conduit, and 5/16"-18TPI All-Thread as an inexpensive lead-screw... Used UHMW 15" x 20" cutting boards from Sam's Club as dirt & water resistant platforms ... 3D-Printed several hole drill guides, which turned out to be a very accurate way to locate & drill mounting holes in the Conduit and UHMW cutting board ... I also uploaded an additional Solidworks Assembly Version of the Lift with Extra Supports to limit Side-to-Side sway :-)
