Model information
Description
Cover for the electronics of the Traxxas Slash LCG 4WD that maintains access to the battery swap and the ESC operation. The source describes two variants depending on the position of the ESC button: one for the old 3355X, with visible capacitors, and another for the 3355R. It also offers two solutions for the front intake: a grille with filtering material or a solid piece which, according to the author, does not filter dust from the air. The rear fan is the original Velineon, oriented to exhaust air.
Preparation, compatibility, and printing
The documented assembly uses nine M3 × 6 screws for the grilles and another M10 × 6 for the connector cover; one M3 × 10 in the front, two M3 × 20 on the side, and four M3 × 10 with four self-locking nuts for the fan. The hinge uses a piece of 1.75 mm PETG filament. First select the ESC variant and check access, wiring, and ventilation. No waterproofing or a complete print profile is certified; keep the air inlets and outlets clear.

Cover to protect electronics inside the Traxxas Slash
The idea behind this model is to protect the electronics from dust and debris while keeping the car easy to operate:
-
no need to remove the dust cover when changing the battery
-
no need to remove the dust cover to start or stop the ESC
-
added active cooling
There are two versions of the dust cover, differing in the position of the button used to control the ESC. This depends on the ESC version. The old ESC 3355X has visible capacitors behind the wires, and the button needs to be positioned slightly forward. The new ESC 3355R has no visible capacitors, and the button needs to be positioned slightly backward.
The front air intake (cooling grille) also has two versions. You can use a piece of fabric (I used an old vacuum cleaner filter), or print a solid filter, which is simpler but does not remove dust from the incoming air.
The fan used at the back is the original Velineon ESC fan, installed to blow air out of the cover.
The hinge for the switch lever is made from 1.75 mm PETG filament.
All bolts are M3:
-
to fasten the cooling grilles: 9 pcs of M3 × 6
-
for the connector cover: 1 pc of M3 × 6
-
to fasten the front of the cover to the chassis: 1 pc of M3 × 10
-
to fasten the side of the cover: 2 pcs of M3 × 20
-
the fan is mounted with 4 pcs of M3 × 10 + 4 locknuts
