I needed my honeycomb bed higher, so I made a set of 100mm risers for it.  I raised my laser for a rotary set-up (see risers set for that in my profile), and changing out the legs on the laser every time I want to use the rotary seemed inefficient.  So, I made a set of risers to put under my honeycomb bed since I take it out every time I use the rotary.  Made more sense to make the transient accessory have risers, then to take the time and trouble to raise and lower the whole laser frame each time I want to use the rotary.  So much easier to do the honeycomb instead.
