Extension Bar Holder

My first design made for holding 5 extension bars. Pause printing at 7.8mm and 9.4mm to insert magnets (60mm x 10mm x 3mm - 3 required).

Extension bar sizes are:

(h) = Head end
(l) = Total Length
(b) = Bottom end

12.40mm(h) x 279.5mm(l) x 8.1mm(b)
12.40mm(h) x 210mm(l) x 8.1mm(b)
12.40mm(h) x 153mm(l) x 8.1mm(b)
12.50mm(h) x 99.9mm(l) x 8.3mm(b)
12.25mm(h) x 32.2mm(l) x 7.85mm(b)
