Hardware rack

This is my first model from the ground up, I wanted a more secure and bigger rack than what was available online.  Its 250mm tall, 150mm wide, and 268 mm long when assembled, 

Hardware is needed for stacking racks together just a M3 nuts and M3x10 bolt on all four corners, use a drill to get it to slide thru.

The spreader bars are a little fragile and are a bit of a tight fit, but push in and slide down. The racks just slot in to the bars

Let me know if any changes should be made to improve it

Note I used my bambu p1s to print, idk if this will work on a small printer as the p1s has 256x256 build plate, It might need to be scaled down to be made
