Modular Shoe Rack

My sister-in-law had purchased a similar shoe rack that just broke and fell apart, so I designed my own version. This shoe rack is meant to be modular in nature, interlocking each piece to create a new level to store shoes. Also provided are clips that clip each section when building horizontally. The shoe rack base is meant to be printed at scale on the X1C, P1P, and P1S in PETG. The clips on each section are meant to give a little so they snap in place so PETG is a must. Any other filament would proabably break since the fitment is very tight. 

Side panels will go in at an angle:

Then Snap into place, it will take some force so give it a push.

Here is what it looks like with both on:

Back just slips in, the top of the back snaps into the bottom of another base. 

Clips will hold racks horizontally. They are a tight fit.

Added small chamfered edge to square pegs on the side panels for easier assembly. Please let me know if these need to be more aggressive or if these are ok. Thank you!
