The file 'Battery Display For Razor Crazy Cart 3D Printer Model' is (stl) file type, size is 181.7KB.
This Thing is a Housing for a battery display that can be plugged into the charging socket of the Razor Crazy Cart (latest version).
The battery display is a €4 item from Ebay. The plug is a from a GX16 connector. Standard charging socket have 3 item, and that's what you need. The plug is being clamped by a simple M4x16 (or longer) countersunk bolt plus an M4 locknut. You can get these at your local hardware shop.
Don't be irritated by my pictures showing 4 pins. This is because I converted mine to a Li Ion battery, that require a different charger and I wanted to avoid mistaking the chargers.
This item can be printed w/o any support upside down. The bottom of the square whole for the display it not so beautiful then, but you don't see it anyway.
On the pics you see some marks of modifications. Ignore these. This was my initial version. I have modified the attached model so it fits perfectly.
