This is the V2 of the bed extension it is a completly new design for other circumstances.

it has a clean neat fit and a smooth side

I recommend using felt pads because it is a possibility that it can scratch you bedframe a bit and I left room that it is posibble

the size between the pieces is 26mm

it can hold your phone, your charger, your ventilator or your laptop because it is very sturdy even with low infill

if you use low infill I recommend an other fill pattern because otherwise it didn't have a nice finish 

(I tried low infill but i had to start over and with the seccond try with low infill i had to sand it mid print but for the print profile i have a nicer print but lost the image of the nicer printed one)
