159th_Falcon Posted October 9, 2024 Posted October 9, 2024 Hello everyone, On the inside of the hotas warthog base there is an big black ring that carries the big spring. Mine is cracked in like 10 different locations and i need an replacement. So far i have been able to re-design the part in FreeCAD for 3d printing, but i can't take accurate measurements because of the cracks. Would anyone happen to be able to get some accurate measurements for me? (in mm very please.) nullnull [sIGPIC][/sIGPIC] The keeper of all mathematical knowledge and the oracle of flight modeling.:)
Hempstead Posted October 9, 2024 Posted October 9, 2024 (edited) You want to put a taper to the 4 holes... trust me... I CNC milled a solid chunk of 6061-T6 aluminum to perfection... and bought a 5mm reamer and bunch of slightly under 5mm drill bits for the reaming... in an attempt to eliminate the dead center, only to find that that it locked up... and there is a taper of the 4 holes (top of the hole has a slight smaller ID than the bottom of the hole; go measure them with a good caliper yourself). If I have a recommendation... I would say that 3D printing with FDM is difficult to get that precision required for the taper. Resin printing... good luck with all those strong resin like Phrozen Onyx Plus. So, I would recommend that you either mold that 4 holes, or design some metal parts for it (i.e. buy a correctly tapered drill/reamer and dil/ream a brass/bronze tube for the 4 holes. I have the 3D model for it in Solidworks (without the bottom "blocks".), attached. You can grab the accurate dimensions from there. Note that this 3D model has the straight holes, not tapered. This is the one I used to send to MaserCAM to generate GCode and then CNC milled it. The real recommendation? Buy a replacement part from TM.

159th_Falcon Posted October 9, 2024 Author Posted October 9, 2024 (edited) Absolutely awesome. I have been pleasantly surprised by the capabilities of the Bambulab X1C that recently took it's residency inside my home. So I figured it would be worth a try. I have had a very solid NO from Thrustmaster in the past about buying replacement parts so figured it wasn't worth it. (for the same stick actually, needed to replace the cable that runs trough the gimball to the connection of the stick.) And thanks for bringing the taper to my attention, mine is so badly cracked they are impossible to measure. Edit, Free CAD cannot open SLDPRT files. You have it available in any other format?
