Saw at an angle (device for Bulgarians, Fortune, USM)
This device helped me to saw a bundle of rolled metal at an angle of 90 degrees without effort.
Now I'm building a second CNC machine, the working field will be 1050 * 1050 mm. For the frame, I needed to cut a profile pipe and corners. I had a Bulgarian, but I did not want to saw manually, this would lead to big errors. For half an hour I built a simple device that allowed me to cut the metal exactly at an angle of 90 degrees.
I thought for a long time to print the case on a 3D printer or to do it manually. It’s easier to print, but I decided to do the first boat with my own hands. I used cardboard as the main material.
A simple planer from an old chisel, a couple of pieces of wood and two pieces of plexiglass.
Almost all toys bought for the daughter do not cause the child's interest, which can not be said about developing toys made by themselves. Below is a photo of the simplest developing mat, which the wife made for a couple of evenings from old buttons.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
I present to your attention a homemade 3d printer. Assembled from plywood, aluminum, plastic and Arduino. This printer is unique in that its kinematics is peeped from Ultimaker, but done with quality modifications.
