Tabletholder extender

I created an extender piece for the Telescopic tablet holder which I bought on Aliexpress.My car (Kia EV6) did not allow a direct fit due to the headrest design, so to overcome this I needed an extender.(AliExpress tablet holder) Extra requirements:1x M4 35mm screw1x M4 hexnut Advice:Print this piece in PETG to withstand the heat during the summer.PLA wil deform (trust me, I tried)(This piece will carry the weight of the tablet and/or any abuse from the child)
