2040 Extrusion For AM8

thingiverse

This is some 2040 extrusion for the AP8 made by another member, but I had issues getting it to fit T-nuts, so I drew up my own design. Right now, I'm printing it out, and I'll post the final product once it's done. I use 5/16-inch rods from Home Depot that cost $4 to reinforce the inside. I added connectors that fit perfectly, using 3mm set screws to secure them in place. Additionally, I've uploaded my 123D file so you can customize your own length and design. Simply press or pull on a blank 60mm piece to create longer extrusions. After printing a section of the extrusion, I found it to be strong enough due to the four connectors and the 5/16-inch rod. The key to its strength lies in the tight tolerance between the rod and the extrusion. To assemble them, simply place the rod in a drill, hold the extrusion, and slowly turn both until they fit snugly together. Use a screwdriver and small hammer to tap in the last bit of rod, taking care not to apply too much force. I've found that the pins are useless because they tend to break off during assembly, so I won't be printing any designs with pins from now on. The extrusion is significantly more rigid than stock A8 acrylic, making it ideal for building frames. I should have most of my frame completed soon.
