Modular Mario Warp Pipe Planter

So a while back I thought it would be funny to put a Venous fly trap in a warp pipe planter and make a real-life piranha plant. As it turns out, it was funny and actually looked pretty cool. When I made that design, I used my own warp pipe, and a block model that I downloaded from Printables, but had to maodify in Bambuslicer before I could print and use it. After that, I figured it would be cool to have moduler options, so a whole setting could be made from a Mario level for houseplants, but that didn't exist. So, I spent a few hours in DesignSpark and created this whole design from scratch. As stated in the title, the design is modular, but only from a 2D perspective, like in the classic Mario games. So, the standard warp pipe base block does not have modular pegs, the double-sided block has 2 pegs, along with slots on opposing sides, and the single-sided block has a modular hole on only one side, and one peg included in the file. The modular spacer has pegs and holes on 2 sides. The
