Y Axis Carriage 220mm Heatbed Adaptor (CTC A13 Ender 3 to anet a6 a8)

This is an adaptor for using a 220mm x 220mm hotbed, as used in the Anet A6 and A8, on an Ender 3. Extends the height adjustment bolts by 27.5mm diagonally from the hole in the corner of the carriage plate.
You will need to print 4 in total, 1x adaptor per corner.

If you have a CTC A13 or similar, you may find that the heabed consists of a small heat bed, epoxy'd on to a larger build plate. I highly recommend replacing it with either a genuine ender 3 heatbed, or the cheaper Anet A8 bed. Mainly because the CTC version doesn't actually maintain the correct heat across the whole build plate. Which will result in warping towards the edges of the plate, because the temperature drops as you try to print further from the centre. The A8 heatbed is 220x220mm instead of the ender 3's 235x235mm, but using a 235x235mm glass build plate gets the printing area back, without the dramatic temperature drop which causes warping.

4 versions are included:
The 2mm versions are designed to fit the 2mm thick y carriage plate that comes with the CTC A13 Ender clone.
The 4mm Versions are designed to fit the 4mm thick y carriage plate that comes with the Ender 3/pro.
The "Spring" versions are for use with springs and the "Bung" is for use with the silicone bungs as shown in the picture.
