1/120 railbus T1 of GHE 1000mm narrow gauge TTm scale

If you print the following designs, *please* post your make, comment or just tell me. I don't need many of them and a lot improvements of the 3D files and documentation are only made, to give *you* better results. General information are public available and railcar [DR/HSB: 187 001-3](https://en.wikipedia.org/wiki/GHE_T_1) is well known on narrow gauge model railways. A similar rail bus from Dessau was used on the Weimar–Rastenberg railway^{[1(p. 246)] [5]}. Gotha produced slightly different cars for the Mittelbadischen Eisenbahnen AG (MEG) ^[6], maybe we will see something like that in future. I built one from brass about 30 years ago and finally descided to print a full remake in resin in TT (1/120 scale) and do a H0 (1/87 scale) body for a friend. I will *not* create a H0m chassis. Scale the body to 137.93% for H0 scale. You see the print of both in one of the pictures above. ###Back to TT and printing Stay away from Anycubics auto repair feature, it just removes all bolts. The holes in the bottom fit a 5mm x1,5mm magnet from a common cigarette paper brand. You can glue it in with super glue or just a drop of resin and cure it. Its fun using the Wash and Cure station to clue parts. I removed the hooks and doorknobs from the 3D model and added holes. They are fast made from brass wire and it's no fun to replace broken resin parts. I recommend using the half spheres on the inside to add heavy supports, **rotate chimney front side up** -- I added a little cylinder just as light printing support. I recommend the (normal) body with internal supports, because I had some issues with wider lower frames/smaller middle sections. As you can see in the images, I added supports inside the windows and bended them to an additional massive outside support. The Anycubic workshop has several issues on exporting models with handmade supports, so I can't share the version with supports. And now we have Anycubics workshop 3.x solving the export problem but missing options for fine tune manual supports... The coupling is very fragile, so it could be replaced by some brass or just print the spare part(s) ... Windows: Between V13 and V14a the front window changed into 2 separate pieces, the front window and a sun protector shield. So you can print the Windows in clear and the shield in amber. You can expect a TTm chassis soon. So I'll keep the work-in-progress marker. **Updates** 20230330: added Windows 20230323: uploaded my version 14 with and without internal supports. The supports are intended to reduce deformation during printing (especially scaled to H0m). 20230319: <blockquote><p>uploaded V12 with larger light holes, additional small supports for less ugly generated support points</p> <p>added a small do-not-print-Version of body without details as help for motorization</p> </blockquote> 20230312: exchanged the complete version with a repaired version. ###Origin and licensing### For technical drawings look at the sources^[1][2][3][4] below. Some sketches show different measurements. You are free to scale my work and print it for your projects, close friends and your local model railway club or school. But I don't want any commercial use of this design and prints. If you are member of a model or railway club, a school or something comparable with these and want to use it for educational purposes in higher numbers, please tell me. ###Main sources### [1] Kieper, K., Preuß, R. & Rehbein, E.
