Base plate with centre block

About this model

read your script as the dimensioned top view of a base plate and modelled it as a solid part. The plate is 240 × 50 mm. It has four Ø10 mounting holes, 11 mm in from each end, 28 mm apart and centred on the centreline. A 48 × 60 mm central block sits on it and overhangs the plate by 5 mm front and back, so the overall size is 240 × 60 × 30 mm. The drawing gives no heights, so I assumed: - an 8 mm plate and a 30 mm tall block; - the 26 mm lines as a 15 mm deep channel running across the block; - the inner 16 × 30 mm rectangle as a slot through the whole part. Which heights should the plate and block have, and do I have the 26/16 features right? At 240 mm the part is longer than a 220 mm bed, so it lies flat but turned 45° on the bed (footprint about 205 × 205 mm) and prints without supports.
