Holiday Buggy gearbox cover.

Little fettling to do yet

Finished the motor cover for the Holiday Buggy .

Finished Holiday Buggy gear cover is now on Thingiverse for free download , I'll get the second version on Shapeways today .

I've just ordered a set of printed gears for the holiday buggy , SLS printed in Nylon P12 for testing , should be with me in about a week and if they are good I'll add them to my Shapeways shop .

I've just fished cutting up the Holiday Buggy chassis for 3d printing on an Ender 3 size bed , I've smoothed the bottom of all the little ridges and separated the front bumper fittings as a separate part , the two main parts are connected with four M3 screws, two from under the steering servo position and angled upward 45 degrees and one either side of the chassis angled downward , the angles make it easy to install the screws , allow longer screws for greater security and also hide the screws away somewhat . the bumper fitting can also be attached from inside using M3 screws .

Well done!

Test print of front end , its low resolution 0.28 layer height and I'm using up some ancient PETG but it all lines up , I. Printing the rear now but again using up old filament so it's funky translucent blue and won't be finished till morning .

God I'd forgotten how much I hate PETG. Anyway this is the Holiday Buggy chassis complete , it all lines up nicely but its an ugly low res print and I had a little section at the front of the blue part warp up from the bed while I was out walking the dogs doesn't really matter as its never going to be used except as a proof model.

Just found an error , somehow i had attached the transmission 2mm too low , just taken a while to sort out

I really like when test prints are not the same color than the original parts... It really helps people to sense what we are doing here

More Holiday Buggy stuff , these are Pro 3d printed gears I got done to verify the design before they go on sale.

I finally found a 540 motor mount for a reasonable price so drew up this gear cover to mach , its a two piece design .

All the lights , engine and side pods for the Tamiya Sand Rover are now free downloads on Thingiverse
