Since it was a sunny day outside, gathered some tools together along with the painted pieces from the other day

Set out the aluminium square tube on the table

Took out the 3d printed part from the kit and put them in place

Dry fit all the parts to make sure that they fit

Grabbed some 5 minute Epoxy

Mixed the 2 part epoxy on an off cut of acrylic

Put epoxy on the ends of each of the 3d printed parts and the pushed the aluminium onto them
As we can see, this pushed some of the epoxy out of the end..

Once all 4 corners are done, leave out for 5 to 10 minutes for the epoxy to set

These are the screws that are going to go into the holes in the aluminium, further increasing the strength

First screw done!

Worked my way around, putting each of the screws in

All done with the screws!

Now I drill 2 holes in the mild steel flat bar and straight through the aluminium tube

Using a 4mm tap, I tap both the flat bar and the holes in the tube

Screwed the flat bar to the tube using 10mm length M4 screws

Mounted the stepper motor bracket, using M3 10mm screws - dilling the holes and tapping them into the tubing

Drilled two 4.5mm holes and then tapped each hole to 5mm and then threaded these on - they are 28mm apart, 14mm from the center of the motor

Next I place the lead screws in

And then tighten the grub screws, making sure the lead screw is slightly above the bottom

Once that is done, I grabbed the timing belt (GT2) and then worked out where the holes would need to go in the flat bar

When measuring, I made sure that the motor was as close to the tubing as possible

Drilled and tapped 5mm holes into the flat bar

and nearly done!

As we can see there is a little slack in the belt..

can fix this by moving the stepper motor away from the frame

Next time - utilising this 3mm sheet of aluminium to make the bed!
