Cap for Tonies

Related to Tonies stackable and expandable shelf by @Marcus3DLab. Its a great shelf system and kudos for the hard work! I added this end cap to help with keeping washers inside without glue and looks like a flush piece underneath. Its created with 2 walls using PLA and 20 percent infill to help with expanding and contracting. I uploaded the STL and Project file I used. I have included few extras in the project file as in just case. Push this into the hole after the washer is in with little force but not great.
