Are you going to do a modernized version of the Holiday buggy chassis? :-)
No Tamiya already did a re-chassis although I may do some mods to have oil shocks , this mostly started to be able to supply replacement gears so people could get them going again , I'll design a gear cover as well as the lack of a closed gearbox was the cause of needing gears :roll: , not really sure why I'm modelling other parts as this is probably the least loved of all Tamiya cars , it takes a few minutes to find any reference to the old version even on TamiyaClub Forum :lol: anyway I just finished the rear arm model , its not handed so I didn't even have to mirror it .

The thing is lot of people complain about 2 things regarding the re-release : the DT02 chassis required to do some cutouts of the bodyshell because of the shock towers, which are not so nice, and the arms of the DT02 chassis are far too wide for the bodyshell... And for the rest : initially it was mostly a 380 based car, event if there was "Off-road high performance car" marked on the chassis (which is by the way marked on every single Tamiya box, even for the Grasshopper)... Maybe time to make it a real high performance offroad car :-)
There are shorter arms for the DT02 that someone designed but yes the holes in the front of the body are ugly , I've just bought a body (Sand Rover) and I'm going to have to close those holes up , the Sand Rover body is the standard Tamiya hard body material , I want to say Polystyrene ? and can be glued unlike the Holiday Buggy that has a Polyethene body that even paint wont stick too .
The main fault on the older surviving models is the front spring mounts breaking off the chassis so finding a way to add oil shocks to the front would be of use as well , again there is a part on Thingiverse to fix the spring mounts but I'm hoping I can do better .
If a jobs not worth doing then its certainly not worth doing well.

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 .

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.
