FLSun SR - 5015 Blower Fan Adapter [IMPROVED]

This adapter is fully redesigned from the ground up as an improvement over https://www.thingiverse.com/thing:4917075. Like many users in the comments I saw interference issues at the full extent of the print bed using that model.

This adapter works across the entire print bed, includes stiffening ribs on the backside for increased robustness, and an additional mounting hole. I've used it successfully for a couple months.

Instructions

Print 1x of each adapter model and 1x cross bar in PETG, 100% infill + brim, no supports. It's sized for a 0.4mm nozzle.

Use 2x 20mm M4 bolts to secure the crossbar, and you can reuse the existing mounting bolts to secure to the hotend.

You will need to wire the new 5015 blower fans into the printer... if you can find fans with the correct connector, great, I ended up soldering the old connectors to the new blowers.

Go ahead and print these adapters for better fan angle as well: https://www.thingiverse.com/thing:4899374, and I highly recommend the Aurora Tech video on the FLSun SR: https://www.youtube.com/watch?v=BOU88fF1kq0
