Kitty Caltrops - Interlocking Pet Repeller Spikes

Do you have a pet who just can't figure out where their playground ends and your workstation begins? Worried about them getting hurt while kindly "inspecting" your 3D printer? Have you lost one too many valuables to your cat thinking your shelf is a bed? Well, just print out a few of these and place them where you don't want your pet to go - uncomfortable to walk or lay on, they get the message across that this is NOT Fluffy's Spot without you ever having to reach for the squirt bottle!

By default, these print as a 20mm x 20mm square (+3 mm for the dovetail). Scale them up or down as necessary for your pet and your space. The slot for the dovetail is small enough that they should print just fine without any support.
