Tri-Angle Bracket (Complete Side Table)

thingiverse

Here is a joining bracket designed for Design Technology classes to explore different angles in furniture design. This simple part can be combined with wood to create interesting furniture pieces. Update: I've added a Table Top Connector part, which complements the Side Table design. The connector helps restrict outer movement by joining the two parts together. Surprisingly, this table is strong enough, though not quite sturdy enough to hold a person's weight - perfect for a side table. The tabletop was laser-cut from 6mm plywood and stained red to match the printed parts. I've also included the DXF table top file for laser cutting. You can experiment with different leg lengths but the ones I used are made from Mirindy hardwood, 600mm long, with 45-degree cut ends. The profile is 40mm X 24mm - if you cut to these sizes, the design should fit together perfectly. Adding a bit of glue to the table-top connectors will add strength, although it holds well with pressure. Thanks for the great feedback - I've really enjoyed this project! Print Settings Printer Brand: Stratasys Printer: uPrint SE Plus Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2540 Notes: The print came out great on the high-quality setting on our machine. How I Designed This The part was designed on Autodesk Inventor and exported as an STL - the print was successful. Project: Design a bracket used to make a simple coffee table Objectives: Create a simple 3D part to join wood parts in interesting ways Make the part strong enough to create a small coffee table Audiences: Mostly for G10+ students and product designers in Design Technology classes Preparation: Students should study angles, sketch their basic idea, and work out lengths and heights. They should also consider the wood sections they will use as legs. Steps: Firstly, a triangular prism is drawn on CAD software - we used Autodesk Inventor. Then flaps are added in a 'fan' shape to the correct lengths depending on the wood chosen. Holes are then added with carefully measured countersunk sections for the screws you've chosen. The arrangement must be one hole per corner (diagonal) as otherwise the wood parts will get in the way of screwing the screws in! STL file generated and printed Results: This part at 45-degree angle should work fine - all thicknesses are 2mm, and material is ABS. These factors could vary, and students can experiment with the strength of the part by loading weight on the top once the legs are added to see how much weight it could hold.
