Hi there,
I decided to start building the DXU upgrade for my UM2+, however I noticed that the hotend kit found on taobao is not available at this moment and that the alternative aliexpress variant would differ in size. Therefore I was wondering whether it would be possible to acquire the original design file (fusion 360?) in order to make the necessary modifications to fit the SANbrother hotend. Also I would like to slightly improve the design with snap fit casing, countersunk screws and slightly bigger dimension of the fan part attachment.
