A model handle for painting models mounted on 20-40mm round base for example most smaller Warhammer 40k models
inspired of the games workshop "buttplug" but with a M6 x 55 or 60mm bolt and nut to lock the holder instead of springs.
M6 x 55/60 bolt and m6 nut for assembly or thatever inch size fits in the 6mm hole through "holder" (Paint_handle_body.stl)
Glue suggested super glue to fit the "handle"(Painthandle.stl) to the "holder"(Paint_handle_body.stl)
The slider "rails"(Paint_handle_rails.stl) is a tight press fit in the "holder"(Paint_handle_body.stl) requires some force to push in place some glue can be applied but not required.
UPDATE1 - 28/11-17
Added a thumbscrew file designed for M6 Hex key bolt just to glue to the head of the bolt.
no support required unless your printer have problem printing 45° overhang without support.
- added 2 pictured of my print holding a 30mm and 40mm round base.
had no 20 or 25mm based but i assure it will hold them with no problem in the lower part even square 20 or 25mm is no problem even tho it only locks them by the corners..
tried mounting my old metal Necron C'tan Shard of The Nightbringer (40mm round base) on it and it got very top heavy and easy to tip over so use with caution with metal models .
A future update may contain a lid for the "handle" so u can fill it with sand or something heavy so that majority of the weight still are at the bottom for those times u wanna paint a larger metal model.
