Any 3D printer using herpers out there?

I have had a 3d printer for a month now (it is really cool and useful) but so far I've only used it for 1 helpful reptile related print job. I didn't want to pay a dollar a piece for sliding glass door pulls so I made some in cad (easier than you'd think to use) and printed out 11 of them (one door pull was lost when a door was broken). The 11 total cost for material (plastic and double sided tape) was less than a buck for all 11. Other ideas I've tossed around are mounts for branches. Beyond that I can't think of anything that is going to be cost/time effective enough to bother with making yet (hides take too long to print to be worth the effort for how cheap they are to purchase). I might design a custom thermostat enclosure later on (I've used project boxes up to this point and they are passable). Any ideas anyone has for a herp project? I have considered one of the terrarium conversion kits you can find, but don't keep anything needing a terrarium at the moment.
