A few years ago I built the board for my copy of Steve Wards<\/a> Division Controller<\/a>.<\/p>\n

I decided it was about time I built a case for it.<\/p>\n

My first attempts were around 3D printing it and I had designed a relatively ergonomic case in Sketchup<\/a>.<\/p>\n

\"\"<\/a><\/p>\n

I had a few attempts at 3D printing this case, however I was still using my old home made Prusa I3<\/a> and it was really on its last legs and pretty much every attempt failed after about half a dozen layers, plus it only just fitted on the bed.<\/p>\n

I was looking around my workshop (garage) for a suitable container I might be able to use, when I remembered I had a few small sheets of dibond left over from my lasercutter skins<\/a>.<\/p>\n

I spent weeks trying to persuade the supplier of the skins to send me the offcuts from the 8’x 4′ sheet, before they eventually sent me 4 x A3 (297 x 420mm) sheets, which is way less than the offcuts would have been, plus at the time I considered them too small to be of any use for anything.<\/p>\n

I thought that if I use some of this dibond for the skins of the box, all I would need is some sort of frame for them.<\/p>\n

First I thought of using some 10mm square aluminium bar, but then decided on 11.5mm x 1.5mm aluminium equal angle, which is available from my local Wickes<\/a> at \u00a33.15 for a 1m length.<\/p>\n

Here is the frame layout<\/p>\n

\"\"<\/a><\/p>\n

and here are the box skins<\/p>\n

\"\"<\/a><\/p>\n

These could all be cut from a single 297 x 420mm (A3) sheet of dibond<\/p>\n

\"\"<\/a><\/p>\n

I cut the various lengths of angle<\/p>\n

\"\"<\/a><\/p>\n

Then drilled and threaded them to M3<\/p>\n

\"\"<\/a><\/p>\n

Next I cut the dibond skins<\/p>\n

\"\"<\/a><\/p>\n

and cut made the cutouts for the screen and buttons<\/p>\n

\"\"<\/a><\/p>\n

Here is the front panel with the screen and main circuit board attached<\/p>\n

\"\"<\/a><\/p>\n

rear view of the front panel<\/p>\n

\"\"<\/a><\/p>\n

The bottom section of the box with the stepper driver, power supply and DC-DC buck converter (5V power for the LCD screen and PIC controller).<\/p>\n

\"\"<\/a><\/p>\n

In assembling the box I decided that the shortest pieces of aluminium angle that I had cut for the uprights were not required as the box was stiff enough without them.<\/p>\n

The power supply is an old HP laptop adapter that outputs 19.5V at up to 3.3A, it is held in place by a couple of additional strips of aluminium angle.<\/p>\n

The completed controller attached to a stepper motor<\/p>\n
