SquircleStool cnc

thingiverse

The foundation of the stool is crafted from 9 mm birch plywood. In this specific instance, I utilized plywood with light glue. Normally, water-resistant glue has a dark color, but I obtained this material from a special model at a local wood dealer. The construction is not particularly complex, but as I create most of my technical designs using SolidEdge 2D, it was quite challenging to get everything right in 3D. The design allows effective nesting and the legs are glued together from three parts. The seat I acquired some sheets of 10 mm acrylic glass. It's the same material I used for my Bedside-Reading-Lamp "Waveguide" and like with that project, I utilized the feature that acrylic glass can be bent when heated. So, I cut the squircle shape and rounded the edges with a handheld router and a roundover bit, then put the result in the oven. Baking the thing for 10 minutes at approximately 170 °C makes it easy to bend. I used oven cloth and a bowl to create the rounded shape. The seat is secured to the base with 30 mm machine screws. I predrilled the acrylic glass and the wooden base, which provides some rigidity. A reason for using machine screws over wood screws is that it's hard to find wood screws that work with Allen keys. After mounting the clear acrylic seat, the result looks unexpectedly great. I thought about applying a matte finish but settled on painting it instead. Using spray paint, I painted the underside of the seat, which turned out well. Please be aware that the STL file is for viewing purposes only and should not be printed on an FDM printer!
