Qidi Plus 4 vented riser with shelf

Remixed of LuckyBananas riser

I was already using the tetto riser but needed a shelf for my S4 dryer and liked LuckyBananas but didn't want to loose the height or venting which I was used to

I printed in petg using generic petg settings 

0.2 layer

15 % infill

Normal supports touching build plate as only required under the base

Additional height and venting
