40mm to 30mm Fan adapter. Version: R1 Dimensions: 40.3mm x 40.3mm x 26.07mm Status: Complete Last Update: Jan 22, 2016 http://GabLabs.ca Update (Jan 22, 2016) I have made a long-awaited update to this design after previously dealing with apparent flaws that impeded airflow. I changed the original design by incorporating a plate-to-plate cone chamfer concept to enhance airflow significantly and decreased mount plate thickness to speed up print times while conserving material. There are now six distinct sizes available in this upgraded edition. **Printed with pillar supports** Chosen improvements: Plate-to-plate cone chamfer design (boosts airflow) Inner ridges removed (enhances airflow) Mount plate thickness is halved, lowering the amount of material required and shortening print time Update (March 2015) Following multiple trial prints, it proved to be challenging to produce a smooth output due to inadequately supported overhanging elements. Although I was able to yield an acceptable result. Because of its inherent design characteristics, mounting the E3D V6 shroud poses difficulties, primarily because of space limitations for inserting screwdrivers. To address these issues, revisions to this model will be introduced shortly. This piece of work arose from my requirement to increase airflow into the E3D V6 heat sink without relinquishing possession of its injection-molded enclosure. Hence it integrates and enables attaching a 40mm fan on one side by bolting onto another surface while permitting E3D V6 shroud attachment on one end. The up-and-coming upgrade will involve incorporating several design amendments including: - Slender walls to boost airflow significantly - Removal of internal ridges - Reduced mount plates, ultimately shrinking its dimensions Instructions Modeled in AutoCAD
