Pololu A4983 heatsink
thingiverse
The objective is to modify an aluminium profile (e.g., Bosch Rexroth or 80/20) for use as a heatsink for four Pololu stepper motor driver boards. It's uncertain if this plan will succeed. To accomplish this, trim the profile to fit with the A4983 chip without causing short circuits on the board. Attach Pololu boards using chopped tool clips and apply thermal paste between the board and profile while ensuring insulation between clip and board. An optional heatsink fan can be added for improved cooling.
