Hello.

Update:

As my Wanhao i3 basically lasted 2 months of use I now no longer have this printer so I do not plan to do any more work to this design. From my test prints I found the tool holder on the rear needs scaling up to fit the tools (I didn't leave enough tolerance for the holes - I'd scale up by a good 25%), and the left-most mounting hole (when looking from the front of the control unit) needs moving 1mm to the left for a better fit, the right-most hole moving 0.5mm to the left. If someone wants to develop this then they are more than welcome, but my involvement with Wanhao is over for now.

This is a storage trunk I designed to fit on the Wanhao i3 Duplicator (v2 in my case - not sure if it will fit v1) control box. It has two M5 holes in the bottom so can be secured to the two redundant threaded holes for the reel holder.

It locates flush with the rear of the control unit and central with the sides.

It has 3 parts:

Base Box

The base which mounts to the top of the control unit, 2 no. M5 holes in bottom which should (this is where it's untested) line up with the threaded holes on the control unit leaving a pleasing position at the rear, plus a little tool holder for the allen keys on the rear.

Has 4 compartments - useful for spare screws.

Insert

An insert tray which fits inside the first and is removable.

Has 2 long compartments for whatever you like.

Lid

A lid which mates with the insert when inside the base box.

Has integrated parts tray in the underside - good for keeping those pesky screws safe and together when doing work to the printer itself.
