Stand for RC models, for example in 1/16 and 1/10 scale, in various lengths and heights.
Print two bases, two tops and one bridge. For the assembling you will need two M4 bolts (at least 20mm) and two nuts.
My make is base 30, top 90 and bridge 200, ideal for Heng Long Panther or similar (If you like the tank in the photo, check my profile).
