K8400 Heatbed connector box

thingiverse

This device connects a heatbed to a Velleman Vertex K8400 printer, utilizing Anderson PowerPole connectors and Molex KK connections. It's designed to be compatible with Bo_Ris Wire covers for mk3 heatbeds (https://www.thingiverse.com/thing:2255250), but also functions independently as shown in images. You'll need two pairs of 30-amp Anderson PowerPole connectors, which I used, although 15-amp versions will work just as well since they share the same housing. These connectors are ideal for this purpose due to their high amp rating and compact design, allowing them to be mounted in a box or left on a cable and remain consistent at both ends. You can find these connectors affordably on eBay, and you won't need crimp pliers; soldering works effectively. To connect the thermistor cable, look for a Molex KK connector with 2 pins and a 2.54mm pitch. These are cheap on eBay and fit perfectly on most printers. You'll require four M3 screws measuring between 10-12mm in length to secure the housing to the printer. Additionally, you'll need four M3 countersunk screws ranging from 12-14mm for attaching the cover to the housing. To complete the assembly, use glue to fasten the Molex connector housing to the main housing and then solder on the wires that will connect to the motherboard.
