Summary

This is a carriage for a AccuRemote digital depth gauge/indicator. It is designed to fit in between the two extruder shafts on a makerbot.

Instructions

This was the cheapest digital indicator I found on amazon.

It can get a little tricky to see the reading when dialing in the front build plate on a Replicator 2. For the price, I can look close.

If you cannot freely move your extruder with this in place, then there is too much add in your additive manufacture and you could cause harm to your bot.
