WWII French Laffly S15T Artillery Tractor at 1/76 scale for resin printing

French Laffly S15T Artillery Tractor 1/76 scale. Though originally designed at 1/28 I have reworked those files for the 1/76 scale. This head meant “hardening” some parts to still be viable at this scale and merging some parts into a more consolidated form so that delicate parts become supported by the larger. The only part that truly remains delicate is the window screen with its incredibly thin window screen & wipers.

The model has been test printed by me on an Elegoo Saturn 8K printer. Using the basic settings and a layer height of 0.05mm. I include the pre-supported files that I used in the test print so you should get a reliable print. The clean up was reasonably straight forward. I use water soluble resin and clean it in very hot tap water. I did need to use a sharp knife to remove some supports that were running close to the model. So pay attention in cleaning before you cure the model. I was able to remove supports reasonably easily from the detailed subframe with out damaging any of the hydraulic parts. Just take a little care in this part of the process to enjoy the best results.

The models consists of the following files:

Main chassis of the vehicle which includes all the sub frame detail. On the top is a stowage area with lots of useful kit represented. Including a crate of wine.

Road Wheels. Print 7 of these as one is a spare on the rear of the hull.

Obstacle Wheels. You need 2 and these glue just below the front number plate. Use a tiny amount of greenstuff to assist in their gluing on.

Window Screen. This is delicate. Print twice just so you have a spare. Remove the ulta-tiny support off the Wipers first at the bottom where it comes up from the window frame. Whops don’t use the Window STLs in the zipped folder but the two separate files. I got the width a little wrong.

Front Driver and Passenger Bench.

Driver. Remove the supports on the steering wheel column first and then the wheel before pulling the other supports off.

Passenger open hands. Add a greenstuff map and he will be useful in the front passenger seat.

Passenger with a wine bottle. Just be careful of the top of the bottle when removing supports.

The first image in the gallery pictures is of a plastic printed version of the 1/28th scale model. I have not assembled the RESIN 1/76 model as it is waiting to go out to the client who originally requested this vehicle in this small scale.

This model was designed by Neal Bowskill copyright September 2020; printed versions of this model have been available since this date on Ebay and has appealed to those who like niche models.
