French Cleats for wall mount

I wanted to start organizing my studio with some wall storage, but I didn't want to drill the wall more than necessary. So I designed and printed this model to hold some spare IKEA table tops I have, they are quite heavy (140cm 10kg and 160cm 12kg) and I didn't find any hangers that would give me the peace of mind to use. 

The wall mount and the wood mount use 5mm screws, the length depends on your needs. If you have a sturdy wall you can use less screws per piece but less than 2 is dangerous. Make sure that your piece is connecting to the wall or wood correctly, in some instances the wood will make a bump and prevent proper contact, in this case unscrew, cut or file the outside excess and put the screws again. For my case I placed 3, but you might want less or more.

The wood stub is just to make sure the table top is aligned vertically as well. They also help to avoid the table to swing which can make the wall screws loosen over time

I've printed these in PETG with 20% Infill and Infill Line Multiplier set to 2, they are very sturdy, I didn't even need to reinforce the models but your mileage may vary

I've also added a soft material (EVA foam sheet) just to help with alignment and to avoid damaging the walls
