Download Free 3D Model Renkforce RF100 Part-Cooling duct 3D Print Model

Summary
I found the available fan-attachments for the RF100 to take up to much space around the printhead, or simply don’t produce enough airflow.
This cooling solution utilizes a radial fan design and can be attached to the printhead using already existing screws on the sides of the head.
It adds just about 15mm of depth and about 8mm of width to the printhead, so you can still extend the RF100s 10x10x10cm print area a bit if you like.
Post-Printing
Mounting
After printing and getting rid of support materials, unscrew the screws on the front and bottom of the printhead(behind the heaterblock on the 45 degree angle part), then attach the duct to the printhead using the two screws you removed earlier.
Attach the blower-fan (I use a Delta 5015 compatible model) and secure it to the printhead using either tape, or the provided mounting brackets (TODO: design mounting brackets)
How I Designed This
Designed in Fusion360 spending a lot of time measuring the printhead, printing, attaching, cursing, adjusting and reprinting.
