Roller Back stopper for PiBurn V3 and V4

We recently introduced new backs-topper with roller instead of wheel for our PiBurn Rotary Attachment.

This new stopper has two improvements over the old one:

• Tall roller profile now can make contact with object that has opening in it (for example if you are engraving a bottle or a wine glass that's been turned around 180)
• It can be adjusted further back to allow more of your object surface to be on the back wheels

IMPORTANT: We when purchasing you will be asked for 2 options, first one is for back-stopper roller with arm only and second one is for the new "platform". Check if you need a new platform as your PiBurn might have one. If your platform is metal and has 3 holes on top, it's a new if it only has 2 wholes or plastic than you have a choice to order new platform for $10 extra. This is completely optional as new roller will work with any style of platform!
