BabyDan No Trip Safety Gate - stopper for one-way opening

I'd lost the stopper to prevent the gate from opening in both directions, so I thought I'd design and print my own. Hopefully others will find this piece useful too.

I printed this as follows:

• Material = PLA
• Layer height = 0.2mm
• No supports required
• 15% infill

It may be compatible with other BabyDan models, however I've only been able to test with a No Trip Safety Gate
