This kit does not increase print size, and requires the addition of an ATX power supply (MCM Part# 310-0036. Running a heated bed with only the laptop power supply included with the Jr. could damage your printer.
- 6×6? heated bed
- 6×6? Kapton square
- ATX power supply (if you don’t already have one)
- Y-Power adapter
- Jumper for your ATX power supply
Technically, you can already extrude ABS with the Ubis hotend on your Jr, but it won’t stick unless you have Kapton and the bed is heated to 75-90 C. This kit also reduces the total Z height available to print by a few millimeters.
